Big cleanup of the tests: now all ini files are based on io.ini in the root folder of the test (relying on IMPORT) and all use the same copy of forcing data and dem. When meteo_reading fails, it now properly write which fields failed (it was always writing "P").

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 example data snow heights were given in cm instead of m. Using the "units_multiplier" of SMET, this has been fixed.

The plugin_nodata of SMET was not remapped to IOUtils::nodata. This is now done (both for header fields, ascii data and binary data).

Several bugs have been fixed in Coords: the setEPSG was not working, the altitude was not displayed with the << operator and the formatting of decimal_to_dms was broken in its handling of seconds...

The documentation for the resampling has been expanded and several other modules' documentation have been updated so their structure is built along the same lines. 

An error message in IOHandler (when failing to load a plugin) was not clear and has been changed.

Several bugs in SMEIO have been fixed (improper column names mapping, improper handling of easting/northing, unclear error message).

The example data set has been tagged as GMT+1 and the meteo_reading and 2D_interpolations modified accordingly (so the argument read on the command line is assumed to be in GMT+1 too)

The EPSG get and set methods have been added to Coords. The "<<" operator has been redefined for ConfigReader (this is convenient for debugging). The SMETIO plugin has been updated (so that it supports EPSG codes and also to change some column names and improve the foutput formatting). Some documentation has been added and the example data set has been replaced by a data set suitable for the whole Switzerland and in SMET format.
