Re-worked the identifly method to get rid of some of the bugs.
added contrast threshold input from gui and showed default values for contrast and size threshold and displayed Error when non integers are given
created the slider for precisely what the threshold is
Checked contrast threshold inputs to ensure they were between 0 and 255.
Working on debugging flydentify, still broken

Changed the insets of the button panel so it does not conflict with the data panel
