How can I implement cylinder geometry

[jacktang]

Hello,

First of all, thanks for the great project!
I've read deepXDE documents, and don't find any resource on user-define-geometry. I going to define cylinder geometry. Just follow the Cuboid source code is ok?

You need to implement all the abstract methods of the base class https://github.com/lululxvi/deepxde/blob/master/deepxde/geometry/geometry.py
