Fixed graphics smash. Refactored program structure and layout.

Commented out a debugging function that showed the mouse point projected
onto the curve. I need to cache the binomial coefficients in a pascal
triangle so bb-form will draw faster.
Added Pre-Cache of Pascal's triangle. Improved point moving.

Right click now locks onto the nearest point and will not jump to any
other points while right is held down. Once released you are able to
press again to select a different point.
