Remove old, unused, too-specific functions

Remove a bunch of functions that were sitting in PseudomodesTTEDOPA
since its creation but were never used, and would much probably never be
used in the future, such as functions for creating initial states for
spin chains, plot utilities or generic-sounding "local operator"
functions that actually returned very specific operators based on the
SiteType of the Index.
