ISLocalToGlobalMapping - mappings from an arbitrary
local ordering from 0 to n-1 to a global PETSc ordering
used by a vector or matrix.
Level: intermediate
Note: mapping from Local to Global is scalable; but Global
to Local may not be if the range of global values represented locally
is very large.
Note: the ISLocalToGlobalMapping is actually a private object; it is included
here for the inline function ISLocalToGlobalMappingApply() to allow it to be inlined since
it is used so often.

ISColoring - sets of IS's that define a coloring

Notes:
One should not access the *is records below directly because they may not yet
have been created. One should use ISColoringGetIS() to make sure they are
created when needed.

PetscSection - Mapping from integers in a designated range to contiguous sets of integers.
In contrast to IS, which maps from integers to single integers, the range of a PetscSection is in the space of
contiguous sets of integers. These ranges are frequently interpreted as domains of other array-like objects,
especially other PetscSections, Vecs, and ISs. The domain is set with PetscSectionSetChart() and does not need to
start at 0. For each point in the domain of a PetscSection, the output set is represented through an offset and a
count, which are set using PetscSectionSetOffset() and PetscSectionSetDof() respectively. Lookup is typically using
accessors or routines like VecGetValuesSection().
