Erlang 2-way Map
An interface is provided which takes an Erlang data structure module name
that contains a dict API to provide a 2-way map. The maps module is
supported despite not providing the dict API. The resulting data structure
would be used when 2 different key values need to refer to the same value
(e.g., using both a UUID and an Erlang pid to reference configuration data).
