##### SUMMARY
`get_url` inherits from `add_file_common_args`, which includes `unsafe_writes`, however our call to `atomic_move` does not pass this argument along.

''' read the modules parameters and store them globally.
    This function may be needed for certain very dynamic custom modules which
    want to process the parameters that are being handed the module.  Since
    this is so closely tied to the implementation of modules we cannot
    guarantee API stability for it (it may change between versions) however we
    will try not to break it gratuitously.  It is certainly more future-proof
    to call this function and consume its outputs than to implement the logic
    inside it as a copy in your own code.
