Detailed Description

SolutionTransfer derived class which is specifically for transferring solutions back and forth between a VolumeMesh and its associated BoundaryMesh.

That is, when calling transfer() below, we must have either:

.) Transfer from the boundary of a VolumeMesh to its associated BoundaryMesh, or .) Transfer from a BoundaryMesh to its corresponding VolumeMesh.

Because of this assumption, we can use the interior_parent() to directly define the mapping between solutions. The transfer() function internally determines which direction the transfer is going, and calls the appropriate algorithm internally.
