Detailed Description

TransferMap represents a mapping of degrees of freedom from a source GridFunction to a destination GridFunction.

This map can be constructed from a parent Mesh to a SubMesh or vice versa. Additionally one can create it between two SubMeshes that share the same root parent. In this case, a supplemental FiniteElementSpace is created on the root parent Mesh to transfer degrees of freedom.
