A stupid bug has been fixed in SMETIO: the OSWR was not renamed as RSWR anymore. Otherwise, small documentation fixes.

The == and != operators have been added to the arrays (easier for debugging). Array4D was not included in MeteoIO.h and has been added.

Trying to help the compiler use SIMD instructions for some array operations. Small documentation improvement for IMISIO.

In order to implement an efficient and portable object serialization, it has been decided that all serializable objects would be manually serialized to an std::iostream. Then, the parallelization framework (mpi, popc, etc) can take over this stream and move it to another node. Therefore, the operators "<<" and ">>" are now reserved for serialization (as seems to be standard) and the debug outputs are obtained by printing "object.toString()". This means that all debug code has potentially to be fixed, by replacing "std::cout << object" by "std::cout << object.toString()".

After compiling with -Weffc++, it appeared that lots of things could be done in initialization lists. Some of it has been done for this commit (but quite a few remain).

Improved error message when reaching outside of an array in debug mode and fixed a stupid allocation bug (swapping two lines in the last commit triggered this bug)

The checkEpsilonEquality method has been implemented as a specialized method for arrays of doubles. This is now used by the 2D_interpolations test. The sun test now calls numdiff for checking the results. 

There were several paths that would built an array while leaving its keep_nodata flag uninitialized. This has been fixed. When resizing arrays, the old content could be kept. This is not really intuitive, so now a clear() is forced before all resize.

Fixed a warning with XCode 4.3 on osX. Tried to make a more standard use of c++ (relying on std::fill for filling vectors, relying on vector.resize(sixe, value) instead of manually initializing a vector, etc). A few more const added where appropriate. It makes the benchmarks slightly faster...

An extra check on the timestamp has been added in SMETIO in order to throw an exception for duplicated timestamps or non chronological order (as happens with daylight saving time). Some private methods in libinterpol2D as well as some () operators for the arrays are now inline in order to help autovectorization find more potentially vectorizable code (and it finds some more). An arithmetic exception could happen in FilterRate (division by 0) and has been fixed.

Better error messages when compiling in debug as well as for dimensions issues (adding arrays of incompatible dimensions, invalid subset, etc)

The VW_MAX field was not properly handled in SMETIO. The failure count has been slightly improved in SNIO (to decrease the number of failures when a model could recover: if ILWR is not provided but TSS is, we don't count it as a failure anymore). 

The implementation of the krigging is moving forward. A bug has been found and fixed in Fit1D, a variogram is now computed (but not using a true covariance, which prevents our krigging from properly working). 

The #define NOSAFECHECKS have been deleted and replaced by a definition by the CMakeLists when in debug mode. This means that when compiling in debug mode, the code will be quite slower but will properly check and report out of bounds access in tables and matrix.

The treatment of NODATA points in Arrays is now controled by a simple boolean, set using "setKeepNodata". This should be easier than the previous commits that require a special type for how to process NODATA. The arrays are also now properly marshaled (ie: the keep_nodata flag is kept through marshaling).

Fixed some warnings that appeared with the previous commit. A missing method has now been implemented in Array3D. The example io.ini is now up to date with the code structure (ie: looking for the plugins in the proper subdirectory)

The nodata handling strategy was not thoroughly implemented: aritmetic operators were not compliant. In order to fix it, a property now records how to handle nodata for each object. A setter method is available. All operations now properly handle it.

The Grid2D and Grid3D objects now have a (x,y) and (x,y,z) method for direct access to their gridded values. This should make it easier to switch a Grid object with an Array in a piece of code.

With the latest changes in CMakeLists, the examples could not be built anymore. This has been fixed in the examples Makefile (but the io.ini plugin path stil has to be fixed).

A new version of the fill method for arrays has been implemented: it only takes a sub-array and the lower left coordinate where to insert it. The file reading optimization that has been implemented in GeotTop and SNIO has also been implemented in SMETIO.

The POPC version has been heavily transformed. Since we would need IOManager has a popc object and this is quite hard (we need a backreference in Meteo2DInterpolator), all parclasses have been removed. Instead, the user will have the responsability to packaged IOManager in his own parclass if needed. This makes the code simpler and skips difficult issues...

A new fill method has been added to the Array2D and Array3D templates that does the reverse of subset (ie: reassemble arrays).

Better error messages have been put in SNIO.

A new Date setter that takes a Date object has been created.

This version does NOT correctly compile with the autotools (it leads to a segfault when running code using MeteoIO), but the cmake compiled library works fine.

The array getSum() was not the most appropriate method... It has been replaced by a getCount(), which means that to really get the sum, one has to do getMean()*getCount().

A new Coords::isNodata() method has been implemented as well as the possibility for two Coords objects to be equal if both are nodata. This is now used in SMETIO so that if the position of a station becomes nodata, it won't force its position information into the data section.

Some comments have been cleaned up in IMISIO, better exceptions thrown in SNIO and better backtrace formatting in IOExceptions (this being only for Linux, a dark grey text color has been specified to more or less make the backtrace less intrusive and scary to the user).

More Visual C++ tweaks in CMakeLists

The Array::getAbs() and abs() methods were not offering nodata handling, this has been fixed. A new getSum() method has been implemented for arrays (with proper choice of nodata handling)

First batch of fixes for issue 68 (variable names starting with "_" invalid for some versions of Visual C++)

The Arrays now skip some unecessary tests in resize(). Since the arguments are unsigned, there can not be any negative size! This also now allows setting size to 0. A new "operator" has been added to get the absolute value of an array. This unfortunatelly generate a warning for unsigned arrays despite that the necessary signedness test is performed. This warning will have to be disabled one way or another.

The example data set has been brought back to SMET version 1.1

The getMin(), getMax() and getMean() Array3D methods were not working. This has been fixed. The Array2D::getMean() method has been slightly simplified

The arrays are now using the vector filling methods when possible. A specialized template for convertString(unsigned int) has been written. 

A two segments linear fit (for elevation detrending) has been implemented with a fixed inflection point. This is quite primitive but allows the LLIDW spatial interpolation to use it and therefore to behave like the traditional SLF SnowFit program. More work will be needed for fully configurable regression algorithm choice though... 

Some namming issues have been fixed in COSMOXML. A better emissivity handling has been implemented in SNIO to be closer to the original Snowpack (ie: compute clear sky ILWR when no cloudiness/emissivity is given).

More fixes for Visual C++ (but not all done yet) as well as new assignments operators for 1d, 2d, 3d arrays. It is now possible to do something like my2Dgrid.grid2D = 2.; and every cell will be filled with 2.

A new group of classes has been created, under the meteolaws subdirectory. This contains various general meteorological laws, such as a sun radiation model, standard atmosphere, etc

The first implementation (not tested yet) of a non-linear least square fit algorithm has been implemented in the libfit1D. 

Several documentation issues have been fixed (obsolete code examples, etc) and classes grouped by modules. This should help the user to quickly locate the classes of interest. 

The DEMObject subset constructor was broken, it has been fixed. It involved creating a subset method in the arrays classes.

The Coord class now supports using the given UTM zone when converting from lat/long to UTM. If the computed zone does not match the one requested in the io.ini, it prints a warning but uses the user-supplied zone.

A first implementation of readStationData for SMETIO has been done. 

Some documentation has been added for plugin development

Overall all include statements within in the library have been replaced by angle brackets, the default install path for the include file is $CMAKE_INSTALL_DIR/include/meteoio, the meteoio libraries (static and shared) will be installed in $CMAKE_INSTALL_DIR/lib per default.

The plugins will be installed in the subdirectory $CMAKE_INSTALL_DIR/lib/meteoio/plugins

Changed the name of the Date_IO class to Date. In case of namespace conflicts, just use mio::Date to reference the MeteoIO Date class.

The << operator has been overloaded for a few types (Arrays, Grids, Coords, Dates, Meteo and Station data) and the to_String() methods removed (except for Dates because it might make sense there to get a string) as a way to provide easy debugging output. This makes the meteo_reading example even simpler! 

The arrays and grids now have a "print" method that prints their content to screen (usefull for debugging). The Coords class also has this method (as required to print the grid objects).

A "using namespace std" was found in ImisIO.h and has been removed. A few comments/indentation/clean up have been done (including in the doc/examples)

The quality rating sorting was broken and has been fixed. The RH interpolation method was not properly working and has been fixed (using the wrong vector for input data). The naming of the number of stations to be used has been made more consistent between the various algorithms and an improved information output has been added.

The array operators have been added to Array, Array2D and Array3D. Grid2/3DObject also have their assignment operator. 

The IOHandler headers (.h and .ph) have been slightly reorganized so that they look as similar as possible (makes toubleshooting easier)

The ARCIO plugin has been slightly reverted so that it outputs float grids (even if some tools require INT, we NEED floats in our outputs).

New methods have been added/updated in the Arrays (1D, 2D, 3D): getMin, getMax and getMean. They accept an optional argument (either RAW_NODATA or PARSE_NODATA) that tells how to interpret nodata values (as normal values or really as nodata).

The dem usage example code has been improved in order to show more capabilities.

The license information has been added: LPGLv3 headers in all header files, license texts as well as a Linux Software Map entry file.

The installation procedure has been added to cmake configuration files (similar to the autotools)

Tow methods for getting the min and the max value out of a matrix have been added to Array, Array2D and Array3D. The updateAllMinMax of DEMBoject has been updated to rely on that instead of doing it by itself.

The doxygen comments of DEMObject have been fixed and the config.dox (doxygen configuration file) has been fixed (it was not processing .cc files). 

A new (private) methods has been added to DEMObject: safeGet(i,j) that returns a grid value for any (i,j) (so nodata if outside of the grid). This could be the right strategy for correctly computing slope/curvature on the dem even in the case of "holes" in the dem... (to be continued...)

* Changed all function arguments from int to "unsigned int" in CArray2D<T>
* Had to change Grid2DObject and Meteo2DInterpolator to reflect the changes
