Bugfix in a constructor (that was making an error on some systems) and updated the Stefan-Boltzmann constant according to http://physics.nist.gov/cuu/index.html

Two new methods for data binning have been added to libinterpol1D. The krigging now works properly with either an empirical variogram or a variogram computed on the last 3 days of data (the later being currently enabled). But a proper caching of meteo grids will have to be implemented!

the to_rad and to_deg conversion coefficients have been added to meteoconst. Small fixes for popc (missing "using namespace" and more marshaling)

Since the _USE_MATH_DEFINES for Windows was making trouble (it should have enabled using M_PI), the basic math constants have been added to meteolaws/meteoconst.h. Now, please use things like Cst::PI and include meteoconst.h.

More size_t related issues have been found (thanks to the new snowpack server) and fixed. Basically, please remember that any variable used with/for the return value of a call to size() MUST be of type size_t (this becomes specially relevant in 64 bits).

The water triple point pressure has been updated to a better value.

A few functions have been added to the Atmosphere class that are usefull (specifically for Alpine3D snowdrift)

- enhance and simplify sqlQueries. The joint snow_drift query now synchronizes the two stations queried (for example IMIS-snow w/ ENET-wind). The data query is efficient in terms of fetching time, that is 1.58 s for one full year of data (17484 rows a 17 columns) but the first conection may take forever (~50 s)
- disentangle stationID and stationName (staion_code and station_name, respectively, in station2.v_snow_drift_standort); parse/edit station_name to not contain spaces ;-)
- get temperature sensor depths and insert them in vecMeteoData
=> we now have a robust mapping of the MeteoData object (see r549) and can pass meta data to the application snowpack ;-)

More meteo laws have been implemented, alongside new constants. An extra check has been added for the USER spatial interpolation algorithm.

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

Then, the remaining namespace issues with doxygen have been fixed, by enclosing the full class implementation in the namespace (as seen for the libstdc++). This removes all these irritating issues. But the popc version has been broken by the change (as seen in LegacyIO).

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.

A new slope computation algorithm has bee added: CARD It computes the slope using Corripio and then discretizes the azimuth along 8 cardinal directions and the slope by degrees. This should be all that GEOtop needs for its drainage direction (then simply calling a dem.update("CARDINAL")).

The copyright notices have been put in place in all files (headers and cc) with proper attribution of copyright.

The documentation has been improved, specially fixing issue 22. Warning messages of doxygen have been fixed. An example subdirectory has been created in /doc and contains (currently) 2 examples of code using MeteoIO.

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.
