Plex: Now meshes can be created automatically from the command line, and some more fixes
- Changed internal mesh creation functions to operate on a DM instead of
creating a new one so that they can happen with options
- Fixed coordinates in CreateCubeBoundary_Internal()
- Added DMPlexShape for prebuilt meshes
- Added DMPlexIsSimplex()
- Added DMPlexCreateCoordinateSpace()
- DMPlexDistributeCoordinates() should copy the coordinate
discretization
- DMPlexInterpolateFaces_Internal() should be careful to preserve the
lower bound when resetting the chart
- PetscSectionSetChart() should ignore entries that match the current
ones
- Added DMPolytopeTypeSimpleShape()
- Do not require an EGADS model for TetGen
- Detail ASCII viewer shows all labels
- Default viewer shows periodicity
