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++.
