Detailed Description

Evaluates a MultiShapeletFunction.

This is distinct from MultiShapeletFunction to allow the evaluator to construct temporaries and allocate workspace that will be reused when evaluating at multiple points.

A MultiShapeletFunctionEvaluator is invalidated whenever the MultiShapeletFunction it was constructed from is modified.
