Detailed Description

Average from fine intersections.

The objective of this class is to average down information from A^(l+1) to C^(l) but only on the intersection of A^(l+1) and B^(l+1). This class is designed to support class 'LevelGridMetrics' where A is the snapback flux on the old fine mesh, B is the new mesh, and C (= A^l) is the snapback flux on the old coarse mesh. These are the steps (Cr is coarsen operator):

1. Average A^(l+1) to D^(l) on boxes of Cr(A^(l+1)). This step is performed at level 'l+1'. D and the coarsened box layout of A are saved.
2. Now at level 'l', copy to E^(l) on boxes of C^(l). These first two steps are done in the averager
3. Compute mask for each box of C^(l). The mask is the intersection of Cr(A^(l+1)), Cr(B^(l+1)), and C^(l)
4. Copy from E^(1) to C^(1) using the mask.
