NOTE: if you add a new function (or file), you must register it in __init__.py for it to be available under:
e.g.
...
from utils import mkvc, …
...
from MYNEWFILE import MYNEWFUNCTION
This is under the DiffOperators class, which can be inherited with BaseMesh to any Mesh Object.
Cell area and other dimension calculations are included in the TensorMesh class.
Wrote unit tests for cell vol, area, and edges.
