TODO PXP

[ajd213]

• rename pymodule to src. It contains both the code to install the pymodule, as well as a main.c and a Makefile to compile a test binary.

• make main.c accept an argument that chooses between graphs

• for unit tests, add analytics for PXP

• in hypergraphs.c, there is LOTS of repeated code. Functionalise this and shrink down the python method definitions for PXP and hypercubes

• As the name has been changed hypercubes -> hypergraphs, update the GitHub to reflect this

• Update the plotting script example. The get_clusters() function has changed name, so right now it won't work.

Done all except adding extra unit tests for PXP
