First commit, the initial call graph after a couple of hours poking. The naming convention for nodes could use work (i.e. it will fall apart after 9 subfunctions). the DOT language apparently doesn't like underscores in ID fields.
Changed naming convention, DOT accepts hyphens so have seperated the hierarchy using hyphens (will allow us to go greater than 9 on sub functions).

Also, have changed from Dolphins zz_xxxxxxx naming convention to actual memory addresses as I think it might be more helpful in the long run (if we have a mem map as well).
