Detailed Description

template<int dim, class GridImp>
class Dune::MMeshCachingEntity< 0, dim, GridImp >

The implementation of caching entities in a MMesh

The caching entity copys the CGAL face object instead of holding a Face_handle pointer.

A Grid is a container of grid entities. An entity is parametrized by the codimension. An entity of codimension c in dimension d is a d-c dimensional object.
