Massive refactor
Loads of definitions are specifically for Hilbert spaces, will mostly be split off into definitions for normed vector spaces and inner product spaces. The latter basically being the former but defining the inner product norm and using that. This is mainly causing a problem because the spectral theory stuff seems to be down between general normed vector spaces.
