Potentially duplicated args/kwargs with different values

[brandonlind]

The function parallel_read() does not account for instances where there are multiple functions passed through functions kwarg that have overlapping kwargs among them but that are pointing to different (at least two) input arguments - the last kwarg passed to a function will override any previous uploads of that kwarg to the engines.

parallel_read()needs to iterate args and kwargs within the fundict of functions passed to kwarg functions to assert any duplicate args/kwargs have the same value. This could happen when passing multiple functions to parallel_read() within a fundict from create_fundict(), where the duplicated args/kwargs across functions reference a different value for each function.

I would like to work on this.
