Not Collective
Input Parameters#
s - the
PetscSectionpStart - the first point
pEnd - one past the last point

The charts on different MPI processes may (and often do) overlap
If you intend to use PetscSectionSetNumFields() it must be called before this call.
The chart for all fields created with PetscSectionSetNumFields() is the same as this chart.
