Allow for saving maps and calling between maps

[nir-r]

As a user, I would like to be able to treat a map as a function + save maps to a backed-up location (such as one drive folder)

Calling saved maps as functions- done.
Reading maps as text files from the maps folder and exposing them both as functions and as api.
Saving in other locations is a different matter, not expected to be supported... Closing this issue
