        Save this project.

        The project is saved to its current location, identified by the value
        of the *location* trait, unless a new location is explicitly provided.
        The specification of a new location is used to do a 'save as'
        operation.

        If a new location is provided, and a file or directory already exists
        at that location, then an *AssertionError* exception is raised unless
        the overwrite flag is True.  This ensures that users won't accidentally
        overwrite existing data.

        This method requires the overwrite flag because prompting the user to
        confirm the overwrite requires GUI interaction and thus should not be
        done at the model level.

        Note that, because we can rely on the location of a loaded project
        always being set to the location it was loaded from, there is no reason
        to try to force the *location* trait within a saved project to the
        location we are trying to save to.  Instead, we update the value in
        the in-memory version of the project only if the save completed
        successfully.
