Tidied up and simplified the test code in FlowGraphTest to operate on lists of nodes/edges, rather than decomposing the graph
...
When you decompose a graph, each edge only appears once; on one of the nodes it is attached to. This meant our testing was not working properly.
The easier solution is to forget how the graph works underneath, get a list of nodes and a list of edges, then operate on those.

Added the initial implementation of a module (and tests) for generating a control-flow graph from an AST
...
This implementation needs to be changed; it currently uses Meta as a primary key for nodes, but that isn't valid.

Added a large hunk of code in ShowCode that allows us to print out occam programs using the right indentation.
...
The code is messy, and not quite finished, but for now it isn't actually being used. So I'm committing it, ready to be fixed up at a later date.
