typedef enum {IS_COLORING_GLOBAL,IS_COLORING_GHOSTED} ISColoringType;
IS_COLORING_GLOBAL - does not include the colors for ghost points, this is used when the function
is called synchronously in parallel. This requires generating a "parallel coloring".
IS_COLORING_GHOSTED - includes colors for ghost points, this is used when the function can be called
separately on individual processes with the ghost points already filled in. Does not
require a "parallel coloring", rather each process colors its local + ghost part.
Using this can result in much less parallel communication. In the paradigm of
DMGetLocalVector() and DMGetGlobalVector() this could be called IS_COLORING_LOCAL
