\subsection{Detailed Description}
Rotate a pair of arrays which map to a rotated set of indices. Rotation is applied across the first and second axes of the array. This rotation should be applied when one field is mapped onto the other. For example, a tracer indexed along u or v face points will map from one to the other after a quarter turn, and back onto itself after a half turn.
