Refactoring model functionality into JLabelData.  Likely broken.
Tested refactored code, fixed bugs.  Works.
Got rid of JLabelGUIData.cacheSize.  Works.
Can't set cacheSize on new jab file or jab file open in JLabelData.  Works.
Got rid of some more instance vars in JLabelGUIData that simply mirrored the values in JLabelData.  Works.
Got rid on unused instance var previousConfigFileName from JLabelGUIData.
Moved a bunch of prediction methods back to JLabelData, from JLabelGUIData.  Works.
Eliminated unused classifier property from JLabelGUIData.  Works.
Made a few JLabelData instance vars private, b/c outsiders shouldn't mess with them directly.
