"""
Helper function that returns a module system and student_data bound to a user and a descriptor.
The purpose of this function is to factor out everywhere a user is implicitly bound when creating a module,
to allow an existing module to be re-bound to a user. Most of the user bindings happen when creating the
closures that feed the instantiation of ModuleSystem.
The arguments fall into two categories: those that have explicit or implicit user binding, which are user
and student_data, and those don't and are just present so that ModuleSystem can be instantiated, which
are all the other arguments. Ultimately, this isn't too different than how get_module_for_descriptor_internal
was before refactoring.
Arguments:
see arguments for get_module()
request_token (str): A token unique to the request use by xblock initialization
Returns:
(LmsModuleSystem, KvsFieldData): (module system, student_data) bound to, primarily, the user and descriptor
