Added and example on how to create a split Frame.
Re-arranged files in GUI folder so that the Parameters GUI and Plotter
are there own seperate classes.
Added the split window as the top level of the GUI.
Changed the Plotter and the Parameter GUI to be wxPanels that accept a wxWindow as a parent.
Added the GUIs into the Splitter Window. (A little imperfectly though)
Set Background Color of Geometry Plotter to Blue
Changed the sub panels to have their own unique ID.
The Plotter and the Parameter GUI how fit well within the Main window, and
through the use of a refresh button, the plotter can update periodically.
