Detailed Description

Determination and storage of the possible independent transforms introduced by coupledPolyPatches, as well as all of the possible permutations of these transforms generated by the presence of multiple coupledPolyPatches, i.e. more than one cyclic boundary. Note that any given point can be on maximum 3 transforms only (and these transforms have to be perpendicular).

Also provides global index encoding and decoding for entity (i.e. cell) index, processor index and transform index (0 or positive integer) to a labelPair.
