Detailed Description

template<typename C>
class GMAD::Published< C >

Class that provides introspection to its members.

In the parser the keywords in the ASCII files need to be matched to the correct member variable. However, C++ has no introspection ability. This class provides this artificially.

All members need to be added explicitly to a hash table (unordered_map) with the method publish. Note that the name can be different from the actual member name
