/**
 Updates:
 25/08/2011
 - Incorporated MPI, if used.
 02/10/2011
 - Made all outputs to vector output_content critical so they are one at a time
 - A much better way to do this would be to open multiple file streams, and pass those around to be written too directly BUT
 I can't be bothered setting that out as it doesn't change the effectiveness of the algorithm. Whoever inherits this might
 want to sort that...
 06/10/2011
 - Also the run time is twice as long having changed to using vector-lists, so definitely not useful for big runs.
 Fortunately overall runtime is still short.
 24/10/2011
 - Moved MPI_INIT and MPI_FINALISE outside brackets
