Comment (by egourgoulhon):
Replying to [comment:82 tscrim]:
> However, I starting to lean towards reinstating the
`UniqueRepresentation` behavior with initialization using a large random
number via `manifold_constructor`. This will keep memory down with
pickling because of all of the extra data that would need to be
initialized after every pickling within the session.
OK.
>In an ideal world, I think we would implement our own variable system for
the manifolds and hold some kind of global reference to that.
Yes this could be something to implement in the future.

> Question, should override the `__copy__` for the manifold (at least, I
feel there might be some use cases for building two manifolds with a
common base atlas)?
Yes, a use case could be trying different things by extending the atlas of
a given manifold. The initial manifold, arising for instance from some
manifold catalog, could be copied to serve as a reference for the various
trials.
