Goal 1: Generate BEL namespace file using bel_resources.write_namespace.

Arguments to this function:

• values should be a dictionary from keys as entries from Complex ac and the values as 'C', which represents complexes in BEL namespace files
• namespace_name should be 'Complex Portal'
• namespace_keyword should be 'complexportal'.

Goal 2: Create an instance of pybel.BELGraph and populate it with links from complexes to their constituent entities (in Identifiers (and stoichiometry) of molecules in complex) using pybel.BELGraph.add_part_of.
