Re-introduced README.rst file, which is currently just the same as the README.md file because setup.py requires it. I'm not sure of the best solution for maintaining both a README.md and a README.rst is, perhaps pandoc via pyandoc is the answer, but for now they are identical and not that full anyway.
Added a test to test the highlighting of PEPA source code. This now results in many test failures because it is added to the default PEPA test fixture. I have not actually added the code for the PEPA highlighting yet.
Added a dummy implementation of pepapot.highlight_pepa so that the tests now fail because of the unimplemented behaviour rather than because of the missing definitions (thus the tests really are testing *something*).
Added the PEPA syntax highlighter to allow all the PEPA tests to pass once again.
