The plugins are now handled by an object factory, removing the need for the IOPlugin class. Otherwise, small documentation update in GeneratorAlgorithms.

better file structure: all the classes purely focused on data storage (such as grids, dates, etc) have been moved into a "dataClasses" directory. All subdirectories are nhow named similarly to the classes and methods: the words after the first one are capitalized.

Since IOUtils was getting bigger and bigger, all the methods dealing with low level file handling have been moved into a new file, FilesUtils. It remains in the IOUtils namespace. One method has been moved to Date. A few includes have been cleaned up.

This addresses issue 335 by providing data quality output (it has to be enabled at compile time): it reports all points that have been filtered or corrected as well as all points that had to be resampled to replace a nodata value by a proper value (ie resampling between measured points is not reported).

Removing the explicit dependency to libproj, removing the plugins group (empty), fixing some stupid Windows packing bugs

Lots of simplification in the CMakeLists (requirering cmake >=2.8.0) as well as a small documentation update

Adding a link in the documentation, moving libsmet to the plugins subdirectory and small fixes in GRIBIO

The DataGenerators handling of missing meteo fields has been changed: if a generator is defined for a field that is not found in the vecMeteo, it will silently be skipped.

Since some grumpy people seem not to appreciate the graphical message box for exception messages, the ability to turn them off when compiling has been added to cmake. The code for generating such message boxes on Linux purely relying on libX11 is also committed (the boxes are ugly but they don't require more than libX11 and its headers).

We still have to make sure that enabling it by default (that would be the goal) does not make it more difficult to compile meteoio...

The METEO_TIMSERIES and STATION_TIMESERIES have been renamed in METEO_SET and STATIONS_SET in order to better reflect their content. 

The concept of data generators is introduced. A new section has been created [Generators] to define how to generate data for each parameter when everything else failed. Soon, you will be able to generate ILWR directly by declaring it in your io.ini!

All the "#ifdef(_WIN)" have been replaced by "#ifdef(WIN)" for consistency. The message box code for Windows and osX has been reorganized, the console messages are now better colorized and the backtrace comes before the error message itself.

On osx too, the exceptions can now produce a message box. Several warnings have been fixed (mostly signed/unisgned issues)

The reason for the non-functionning popc version has been found: we have to manually set the cxx compiler to popcc.

The plugins are no longer separately loadable libraries, but are fully incorporated into libmeteoio. All classes and facilities that provided capabilites for the dynamic loading were deleted (DynamicLibrary). IOPlugin now holds a function pointer to an instantiation function for children of IOInterface. In IOHandler::registerPlugins() all plugins need to be registered with the key name, the class name, a pointer to an instance of the class and a function pointer to the instantiation function for the class (child of IOInterface). IOInterface lost some complexity and thus the constructor of the base class does not have to be called in derived classes anymore.

The CMakeLists.txt files had to be updated to no longer make separate dynamically loadable libraries for each plugin, but to simply add the classes the user selectes to the meteoio library. 

As a side effect the io.ini key GENERAL::PLUGINPATH is no longer necessary.

The smoothing filters now behave differently depending on the centering that has been specified. The IOManager backreference for Meteo2DInterpolator (pointer this given in the initialization list) has been replaced by a setter.

An invalid flag for Visual C++ has been fixed.

A3DIO is now a plugin like any other, that is built by default but can also be disabled. The plugins are now listed in alphabetic order by ccmake.

Another fix/enhancement for POPC: the libraries now ends with "popc" in the popc version, as the autotools build was doing.

Windchill and heat index have been implemented in Atmosphere.

Some cleanup in the filters, some code moved to ProcessingBlock, so that elements that are not filters can inherit ProcessingBlock and get all that it needs. A processing element has been implemented to multiply by a given constant, another one to add a given offset and another one to correct precipitation for undercatch.

Some invalid doxygen comments have been fixed in MathOptim.

Code updates to GRIBIO (that is far from usable...)

More fixes for POPC builds and type error in Matrix.cc (with abs vs fabs). libsmet was also missing for the autotools...

The POPC compilation is slowly improving... One still needs to force the compiler to popcc, but otherwise it seems to work. Necessary includes have been added when popc is activated. A cmake method for finding popc has been implemented.

Small optimization/clean up in A3DIO for special points reading.

The purely graphical parts of PNGIO have been isolated in a new file, Graphics, that contain the Legend class, a Color namespace and a Gradient class. The gradient code is not so clean yet, but the PNGIO plugin is now much cleaner. The color gradients will actially need some serious re-actoring and design in order to be both flexible and efficient (the odds are, it would be based on a object factory and several derived classes like for libFit1D).

On Windows, static libraries MUST be built in order to get the lib files. Warnings have been turned off on the gsoap files for vc++.

Two new methods have been implemented in IOUtils: bearing(string) that converts a string like "NW" into a numeric bearing and isNumeric(string) that returns true if the given string represents a number.

GSNIO has been modified so that the slope bearing are supported, both numeric and as strings (ie: "SSW" for example). The GSN field "NAME" is also mapped to StationData::name.

Finally, an option has been added to cmake, so the user can chose to compile as static library (now false by default).

And as usual, I forgot to update meteoio.lsm when doing the release...

The installation for Windows as well as the autodetection have been improved (ie: they now work out of the box automatically). The calls to Date::set(0,0) have been removed since we now have Date::undefined.

The CMakeLists were not making Visual C++ happy. This has been fixed. Several types issues have been fixed. The /Wp64 option of Visual C++ has been turned off, since it reports wrongly some things as errors (dixit Microsoft and my own experience).

Cleaning up the CMakeLists, adding a version string as well as a new method: getLibVersion() to get the said version string (with compilation date and time). A BuildVersion cmake macro has been written and will be shared with snowpack (and later with alpine3d).

A new library for dealing with SMET files has been developed. The plugin SMETIO builds on top of this library now. It provides:
- A SMETReader class, to read SMET files and parse the header info
- A SMETWriter class to write SMET files and set the header info

The SMET library (libsmet.h and libsmet.cc) are completely independent from the rest of MeteoIO. They have their own exception handling and helper functions, thus they can easily be distributed to other parties wishing to read and write SMET files with C/C++.

The 1D regression component is now coming into shape: the Fit1D class receives two vectors (of X and Y), compute a specified regression model, then transparently provides modelled values (calling fit1D.f()). Introducing a new regression model consists of implementing this f() method as well as a method computing initial guesses. A new method has been introduced in libInterpol1D that computes the derivative of a data set, given a vector of X and a vector of Y. Another method has been implemented to sort such two vectors in order of increasing X.

Partial pivoting has been implemented in Matrix, and complete pivoting has been started but is not finished yet (it will throw an exception if used).

Spatial resampling has been added. This is still quite primitive (no end-user front end or interaction, only nearest neighbor or bilinear), but can nevertheless be convenient. Since the "round" function call was needed, the VC++ implementation has been moved to IOUtils so no matter what is the compiler, we can use "round" in the code (this is NOT in the IOUtils namespace, but still in the mio namespace). 

Several obsolte comments/hacks have been removed and the DEBUG_ARITHM flag commented out, since it does not belong into a library (this is per process, not per object). The VC++ "equivalent" flag still needs to be checked (ie: is it per process or per object?). A missing "required" flag for cmake for Oracle has been added.

Finally, the lsm file had been forgotten in the last release... this is now in order.

Finally, after learning that DLLs are not libraries but runtimes (at least for cmake), the Windows packaging works. All the generated files are back in lib, and the example Makefile and io.ini have been modified accordingly.

The POPC parallel object version of MeteoIO has been removed: now the library can be compiled with popc so that all marshalling code is present, but it does NOT create a parallel object of its own. This means that the caller is 100% responsible for deciding what should go into its own parallel object.

Some documentation has been updated as well as better error messages in smetio.

The CMakeLists have been reworked according to some comments from the cmake mailing list.

Updated/improved some documentation for SNIO and the min/max/minmax filters. Using relative paths in CMakelists, since this should make VC++ put the files at the correct location.

The CMakeLists should be a little bit cleaner. But the Windows installer still does not work (it does not find the dll files).

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 popc autotools build was not working (I forgot to put the WindAvg filter). This has been fixed alongside some cpack fixes for the Windows packaging.
