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).

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).

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 It has been replaced by a getCount(), which means that to really get the sum, one has to do getMean()*getCount().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)

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 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. 

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

Most of the doxygen issues have been fixed. A few are still left (and we lost the inheritance structure in doxygen).

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).

The plugin's interface (IOInterface) has been slightly modified: readSpecialPoints now returns a vector of Coords. This means that a plugin can provide coordinates as (lat,long) or (easting, northing) or (grid_i, grid_j). All the plugins have been modified accordingly and POINTS and POINTSArray have been removed from Array.h

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 Special_PTS and CSpecialPointsArray structures have been renamed in "POINT" and "POINTSArray" (there was no reason to call them "special points"). 

A few new methods have been added to DEMObject: getPointsBetween that returns a vector containing the indices of all points located on the line between two points (given by their real world (x,y) coordinates), horizontalDistance that returns the horizontal distance between two points and terrainDistance that returns the distance between two point accros the terrain as described by the DEM (ie: going up and down the terrain).

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...)

A minor initialization bug was fixed in DEMObject. The new wind interpolation method has been disabled by default (not safe to use before making sure that it does not create unphysical behavior). A minor optimization has been implemented in libinterpol2D: if the DEM min and max altitudes are know, the median elevation is now used as a reference elevation for reprojections.

The doxygen comments have been fixed and enhanced.

The meteoio_demo program has been updated to fully use the DEMObject.

* renamed functions in Array.h
	SetSize() to resize()
	RemoveAll() to clear()
	RemoveAt() to removeAt()
	InsertAt() to insertAt()
* had to propagate these changes into all files that use class Array

* Changed nomenclature in CArray2D<T> to reflect STL conventions:
	GetSize() renamed to size()
	Create() renamed to resize()
	Destroy() renamed to clear()

1) Array3D implemented on basis of std::vector<T> with two Proxy classes in order to allow T[x][y][z]-like element access; the preferred way though is per T(x,y,z).
 
2) Removed the "operator=" in Array.h, Array2D.h and Array3D.h: it was rendered unnecessary due to the internal data members. the generic copy constructor and operator= implementations are sufficient.

3) Remove all deconstructors in Array.h, Array2D.h and Array3D.h: default deconstructors are sufficient.

A small warning has been fixed in the Inverse Vincenty calculation (possibly uninitialized value, but extremely remote possibility).

The warnings for the marshalling functions have been fixed. Please check that it makes sense!

The doxygen code has been cleaned up in order to fix several warnings and several issues with the generated html documentation.

A constant has been defined for holding the IMIS buffer size (in ImisIO.h).

Nothing special, just some re-indentation in order to make the code lines clear and easy to run and understand.

The whole library has been given its new name and several classes have been renamed in order to better match their purpose. The Makefile has been modified accordingly.
