* Enable Windows DLL / lib creation for the nglib system.

Browse Source 
* Implemented by adding a dllexport / dllimport header for all exported functions to indicate to windows which functions are to be made available via the library.
* System change driven via WIN32 define, making it transparent to Linux builds.
