This new mapping structure is designed to support run-time mesh-to-mesh mapping
to allow arbitrary changes to the mesh structure, for example during extreme
motion requiring significant topology change including region disconnection etc.
A single transform method has been written to govern meshWave transfers
through transformed interfaces. This allows the transformer class to
take care of the different types of transform (e.g., displacement vs
positions), rather than having the waved data do it manually. It also
simplifies the creation of data classes and removes a large number of
functions that do nothing.
Propagation through AMI interfaces and the transformation of wall
normals through has also been corrected.
