Geometry

In order to simplify creation of various particle distributions, a few helper functions with self-explanatory names are provided:

• geometry.chain
• geometry.triangle
• geometry.rectangle
• geometry.square
• geometry.hexagonal
• geometry.box
• geometry.cube
• geometry.ring

They can be used directly to create a SpinCollection:

SpinCollection(geometry.chain(0.5, 6), [0,0,1])
