Description
There are a number of changes we need to do to support 4th order in 2-d axisymmetric coords:
- the transformation from cell-centers to cell-averages changes
- the interpolant we use to get the interface states changes
- the transverse term we use for the flux averaging changes
- modified stencils at boundaries also change
- the diffusion to 4th order is also different

Research direction
The issue names no files or tests; start by locating the axisymmetric fourth-order code paths in the Castro source. Done requires addressing the cell-center transformation, interface-state interpolant, transverse flux term, boundary stencils, and fourth-order diffusion, with appropriate validation for each.
