Detailed Description

This class implements OperationMultipleEval for a grids with mod linear basis ansatzfunctions and a set of interactions that limit the subspaces that are included.

The evaluation iterates over all allowed subspaces and only viewes ansatzfunctions of level > 1 since the level one ansatz function evaluates to 1

This Operation is more efficeint than the OperationMultipleEvalModLinear.
