Notes
FEM: Two points p and q are adjacent if q \in closure(star(p)), useCone = PETSC_FALSE, useClosure = PETSC_TRUE
FVM: Two points p and q are adjacent if q \in support(p+cone(p)), useCone = PETSC_TRUE, useClosure = PETSC_FALSE
FVM++: Two points p and q are adjacent if q \in star(closure(p)), useCone = PETSC_TRUE, useClosure = PETSC_TRUE
