Creates a graph but with no markings on the axis and only with test data.
Cleaned up code for draw trajectories
Made forward and backwards buttons which change which loaded image is currently being displayed.
Formatted and sorted all class files.
Fixed some color dots. Also enlarged them.
Testing with fly images
graph scales correctly, draws grid, and sort of puts labels on axes

Added colored trajectories
Fixed trajectory color bug
Fixed the bug where imaginary flies would be drawn in the upper left hand corner. Also recentered identifying dots on top of flies.
Merge branch 'master' into trackFlies
can correctly write labels for axes and the title (This was a pain to do)
sorted functions
fixed a bug that was preventing the graph from being drawn on the analyzer panel
