The exception was a memory leak error

The internet said that it might be due to stale pointer. The most recent
pointers I added were the bigGraph pointers. Commenting them out caused
it to not crash. Le Sigh

commenting it out vs uncommenting causes it to not crash/crash
Fixed graph bug

Turns out that signals of the type "editing finished" or "argument
changed" on spin boxes are cast on startup? This meant that a call to
twoDTrace was being made before twoDTrace was instantiated? or at least
something had happened to the pointer between startup and first graph. I
shuffled the graph initialization around and it works.
