EC codebase Python library (AKA the "frontend")

Module mapping details:

TODO: remove module mapping code when backwards-compatibility is no longer required.

The below module mapping is required for backwards-compatibility with old pickle files
generated from before the EC codebase refactor. New files added to the codebase do not
need to be added to the mapping, but if the existing modules are moved, then this the
mapping needs to be updated to reflect the move or rename.

The mapping uses the following pattern:

    sys.modules[<old module path>] = <new module reference>

This is because the previous structure of the codebase was completely flat, and when refactoring
to a hierarchical files, loading previous pickle files no longer works properly. It is important
to retain the ability to read old pickle files generated from official experiments. As a workaround,
the old module paths are included below. A preferable alternative would be to export program state
into JSON files instead of pickle files to avoid issues where the underlying classes change, so that
could be a future improvement to this project. Until then, we use the module mapping workaround.
