A new Date::getTime() method has been written. A better error message has been implemented for ProcHNWDistribute. The daily_solar temporal interpolation can now handle daily sums provided at midnight (then assuming they belong to the day that just finished) and the documentation has been updated.

Some documentation bugs have been fixed (multiple links definitions for doxygen). The config.dox file has been updated (in order to remove the warnings for obsolete keys). The parameter exclusion feature has been documented and now supports both a space delimited external file or by keys such as WFJ2::exclude = TA RH HS

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.

Several bugs have been fixed: in the AllSky generator, the cloudiness was still forced to 0.5 (as for debug). The data creators were also called *after* the generators, thus making it impossible to used a created data in a generator. 

The placeholders have been put in place (but commented out) for the cloudiness/tau_cloud/clearness index support in MeteoData. It seems that Kt=clearness index might be the proper way to go, but this is still a messy field. Some comments have been added in the code to clarify the use of such parameters.

The possibility to force the input file encoding has been added (for broken XML files) and several bugs fixed when reading all files in a directory

In COSMOXMLIO, it is now possible to choose between using the station location or the model location with an argument in the ini file

small fix to support slightly different naming schemes between IMIS and MeteoCH (with an optional switch to enable it)

Code cleanup and adjusting to the MeteoSwiss naming scheme as well as VW_MAX vs VW trick (VW is Kalman-corrected and therefore can get higher than VW_MAX).

The COSMOXMLIO documentation has been updated and the plugin can now read all files in a given directory (but they must follow a loose naming scheme). Otherwise, small fixes (documentation typo, constification).

First version of the new COSMO (in fact, FieldExtract) plugin. It currently only reads data from one single file that is provided as argument, but this file can contain all the stations and all the time steps. This plugin only relies on libxml2.

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.

Fixing some warnings for Visual C++ and also using ostringstream instead of stringstream when appropriate

More size_t fixes (ie trying to be consistent) and a bug was found when spatially interpolating using a few specific algorithms that would not reset their internal vectors between two calls (thanks Matteo for helping uncover this bug!)

In order to try to be closer to the spirit of the STL, now the empty strings/vectors/lists are tested with .empty(), the first/last elements of vectors accessed with front()/back(), the empty strings are not contructed with string("") but with string(), etc This makes a benchmark based on meteo_reading ~4% faster and this makes the code suprisingly easier to read. 

Some extra constification took place as well as some minor code cleanup (optimizing the comparison between two vectors in order to perform less tests, etc).

The Date class can now properly generate and parse full ISO timestamps, including time zone information. The full specification is now supported by convertString() with a helper method in the Date class. Ouputing an ISO string with its time zone is done by requesting the ISO_TZ format.

Some warnings have been fixed in the tests and all 'string tmp=""' or 'tmp=""' have been replaced by either an empty constructor (that does the same ) or tmp.clear() (that does the same too)

The Date class has been revereted in order to compute year, month, day, etc since this is useful when debugging. The external includes that are used for the plugins are now included as system headers in order to avoid generating warnings for some code that we are not responsible for.

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.

Outputs that were used for warnings (or information) are now done on cerr instead of cout, in order to avoid poluting the outputs of user code. Should we do the same for the exceptions?

A new method, getSolarTime has been added to SunTrajectory.

The usage of SMET for giving special points was not documented. When giving OLWR in SMET, TSS was computed but could lead to an arithmetic exception. PNGIO could throw an exception without freeing all the png_* memory, this has been improved. A few HACKS have been fixed/removed.

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.

A lot of writes were using std::endl for end of line, which forces a buffer flush. This lead to a visible performance cost (as shown by the profiling project made in collaboration with HES_SO). These have been replaced by "\n" that lets ostream manage its buffer as it wants.

The "RateFilter" filter has been renammed "FilterRate" in order to be more consistent with other filters (this does not change anything user-side). A new filter has been created, HNW_MELT. This applies the Snowpack criteria on a precipitation measurement: if relative humidity is not high enough or TA and TSS too far apart, it is considered that any measured precipitation comes from snow melting in the (unheated) rain gauge, therefore the measurement is deleted.

The last occurences of NROFSTATIONS have been deleted in BormaIO, closing issue 163.

Some code cleanup took place in CosmoIO and FilterMax.

In IMISIO, a new option and behavior has been implemented to properly manage precipitation measurements: ANETZ stations keep their HNW (they are considered reliable). IMIS stations by default don't produce HNW anymore. A key (USE_IMIS_HNW) can force using them, but a detection of winter conditions (ie: TA>0 and TSS>0) removes measurements known to be invalid. If neither TA nor TSS are available, then HNW is deleted (in order to prevent injecting HNW=0 in the system during a freeze event if the station would happen to miss TA and TSS). USE_IMIS_HNW should always be followed by the HNW_MELT filter.

Because POPC does not properly support std::cout and requires cout instead, this has been fixed in the code, with the necessary "using namespace" added. Only one std::cout remains (in IOUtils) and will be removed if absolutely necessary later.

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 vw_max field has been added to CosmoXMLIO, and the plugin has seen some cleanup in its comments. Additional comments in Sun.cc should help understand acceptable values for several radiation parameters. 

A bug in SMETIO has been found (it was looking for METEOPATH in the input section even when smet was only used for outputs) and fixed.

Fixed a few compilation warnings found on Illusion. The buffer centering has been introduced in BufferedIOHandler: the user can specify centering as a fraction of the buffer size or as a duration before the requested date (when rebuffering). The documentation has been updated accordingly.

Debugging output cleanup in CosmoXML.

Write meteo data: OK

Read station data: implemented.
In this routine, the user must choose (= comment/uncomment) he we write every station or if we use the given date to filter which station are written

Notice: have to check how dateStart and dateEnd are chosen if we provide a single date (eg in meteo_reading.cc)... Now it takes "date - 6 hours" --> "date + 15 days - 6 hours"
