Detailed Description

This class specializes the MAST::FEBase class for level-set applications where integration is to be performed on a sub-cell inside an element.

This requires that the quadrature be initialized using the points in the sub-cell, but evaluated on the parent element. This way, the shape functions of the original element are used, and the quadrature weights (JxW) are provided by the sub-element.
