Detailed Description

Class for interpolating cell-centered data to the EB centroid.

Various interpolation methods are supported, where some are supported by explicitly expressable stencils and others through limiters.

This is a per-level class without AMR functionality. On coarse-fine interfaces near the EB the user must fill the ghost cells prior to the interpolation.
