A new IOUtils::getCWD() method has been created, a new Config::getConfigRootDir() has been created (to help resolve relative paths) and is now used for the ADD and MULT filters as well as for the EXCLUDE feature of PSQLIO and IOHandler.

PSQLIO: Adding documentation. This plugin is still under development. Syntax of queries will very probably change! 

Fixed a documentation issue in GeneratorAlgorithms, fixed a warning in config.dox and wrote some documentation for the PSQL plugin. Some cleanup also took place in the PSQL plugin.

PSQLIO: Adding explicit copy constructor and assignment operator to get rid of warnings regarding the psql pointer.

[INPUT]
METEO = PSQL
EXCLUDE = exclude.txt

The exclude file has the structure:
stationID, RH, TA, ...

The parameters will be shadowed and set to IOUtils::nodata

Removing an external include out of the PSQLIO header (just in case), updating/fixing some plugin documentation (PSQLIO and GSNIO).

The cmake files for compiling with LibXML++ have been updated since they would not work with more recent Linux (but we should consider dropping LibXML++ and only rely on LibXML2 in order to reduce the dependencies and package finding mess). The special points are now called POI (Points of Interest, like for a gps device) in order to make them more familiar.

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.

A new plugin appears: GRIBIO, to read GRIB files (see issue 19). This is still extremely preliminary alpha code (enough warnings?!), but it should (hopefully) quickly evolve. A small naming inconsistency has been fixed in template.cc and all plugins now keep a reference to a Config object instead of a full copy (which means that the only full copy of a Config object should now be in IOManager and all other components should have a reference to it). 

This addresses the 2D part of issue 168: the ability to specify which meteo parameter and time step to read/write from/to a 2D grid. This should be the prefered reading method in the future, since it leaves to the plugin the task of building the file name, extension, database table, etc This also provides added metadata and more control over the writing process.

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.

Fixed some bad naming in DynamicLibrary, silenced an unnecessary warning from Visual C++ (urging us to use non standard library calls), fixed some DLL exports for Visual C++.

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).

The changes to the IOInterface (no more vec<vec<StationData>>) have been propagated into all plugins.

BUGFIX: When adding a key on the fly to the ConfigReader object it disappeared when accessing it in a plugin. Reason: The dynamic instantiation used the filename parameter in the constructor of the plugins instead of the ConfigReader object itself. Architectural change inside DynamicLibrary was necessary.

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

A new plugin has been introduced: PGMIO that reads/writes PGM graphic files as 2D grids. (using the template plugin, it took less than 30 minutes for implementing the write2Dgrid!!)

More documentation has been updated/added, the template plugin has been fixed for some issues, the example io.ini shows more plugins usage.

General cleanup: the time.cc example sets a timezone variable, an unnecessary "mio::" has been removed in Coords, and two template files have been added to help plugin development (and mentionned in the documentation). 

The cmake targets have been changed into "safe", "optimized", "par" and "hera". (the later being specific for the hera cluster).
