Restores the global dof indices associated with the closure of the given point within the provided sections.
numIndices - The number of dof indices in the closure of point with the input sections
indices - The dof indices
outOffsets - Array to write the field offsets into, or
values - The input values, which may be modified if sign flips are induced by the point symmetries, or
If idxSection is global, any constrained dofs (see
DMAddBoundary(), for example) will get negative indices. The value
of those indices is not significant. If idxSection is local, the constrained dofs will yield the involution -(idx+1)
of their index in a local vector. A caller who does not wish to distinguish those points may recover the nonnegative
indices via involution, -(-(idx+1)+1)==idx. Local indices are provided when idxSection == section, otherwise global
indices (with the above semantics) are implied.
