Detailed Description

When viewing the BoundaryIndicator as the characteristic function of a subset of the boundary then it is somewhat natural (and straight forward) to form multiplication operations with indicators and GridFunctions.

chi * f

This template already handles double-wrapping with the EntireBoundaryIndicatorType.
