Cryptic error message when a 'delta' of incorrect shape is given to 'HoppingKind'

When providing, for example, ((0, 0), a, b) to HoppingKind when a and b are 1D lattices produces the error code Matrices are not aligned.

This error code is not specific to the application domain, and should be improved. I would imagine similar things will happen when a and b do not have "compatible" types of tags.
