Transformations and Symmetries in BurrTools

A transformation rotates and mirrors a shape inside its spacegrid.

That means the transformed shapes again resides completely within the grid. Transformations are normally completely opaque to the user. They are simply a number that corresponds to one posible rotation. Some things are rules though

BurrTools uses a concept that I call Symmetries. Throughout the sources the word symmetry can mean either of 2 possible things:

For each shape we can calculate such a list of transformations. There are some things to keep in mind:
