18 : : * \brief A simple class for meshing geometric vertices
19 : : *
20 : : * INPUT: one or more ModelEnts representing geometric vertices
21 : : * MESH TYPE(S): MBVERTEX
22 : : * OUTPUT: one mesh vertex for each ModelEnt
23 : : * DEPENDENCIES: (none)
24 : : * CONSTRAINTS: ModelEnts must be geometric vertices, i.e. with dimension() == 0
25 : : *
26 : : * This class performs the trivial task of meshing geometric vertices. Typically there will
27 : : * only be a single instance of this class, and therefore it is pointed to and managed by MKCore.
28 : : * It will also be inserted into the meshing graph during the setup phase of most edge meshers.
29 : : *
30 : : * The single instance of this class stores all the ModelEnt's representing geometric vertices,
31 : : * and after execution, an MEntSelection entry for each geometric vertex and mesh vertex pair.
