Summary

This PR adds overset_mask for MLEBABecLap, which already exists for the non-EB version.

Additional background

The PR adds a test case (Tests/LinearSolvers/EBABecLapOverset), derived from Tests/LinearSolvers/CellEB. The test solves the same problem twice: first without an overset_mask, and then with an overset_mask applied over a region specified in the inputs file. It compares and plots the two resulting solutions.

Checklist

The proposed changes:

  • fix a bug or incorrect behavior in AMReX
  • add new capabilities to AMReX
  • changes answers in the test suite to more than roundoff level
  • are likely to significantly affect the results of downstream AMReX users
  • include documentation in the code and/or rst files, if appropriate
