Public Member Functions
	MeshTopologyState (const Mesh &mesh)
bool	same_topology_as (const Mesh &mesh) const

Detailed Description

Simplifies checking if the topology of a mesh before and after an operation is the same.

It does so by remembering the topology of the mesh. In common cases, this can be done without additional copies in constant time by using implicit-sharing.
