Detailed Description

Mesher generating 2D elements on a geometrical face taking into account pre-existing nodes on face boundaries.

Historically, NETGENPlugin_NETGEN_2D is actually 1D-2D, that is why the class is named NETGENPlugin_NETGEN_2D_ONLY. Renaming is useless as algorithm field "_name" can't be changed
