CP Code Wash before Refactor

.. the CP plot curve is a terrible mess. Mostly from
   having multiple significant updates from a number
   of notable developers; Sean, Dan, Mark and Damien
   have all made significant contributions.

.. But the code contains lots of 'smells' and is very
   difficult to follow and update

.. this update makes no functional changes but is put
   in place before overhauling the code related to
   "calculating" and plotting the different curves.
CPPlot.cpp C++ Code Prettify

.. with astyle --style=kr and a little bit of manual editing
