\brief This class handles a set of arrays which can be identified by name tags
This class is a Container of arrays. The arrays can be accessed by specifying a name,
or whole groups of arrays can be selected using select an regular expressions.
Regular expressions are not fully implemented at the moment. Instead, selections are performed
using wildcard compare.
Be aware that you might specify as typename if you define a container, array or iterator!
There is currently no suppurt for user created groups, but will follow later.
This class is relatively outdated and only used in csg_boltzmann!
