JavaRL bugs (08-09-02 code)
	rules exported incorrectly (extra '=' that Excel misinterprets)
	need ability to store current state (value hierarchy, search parameters, etc)
	need ability to import previous states
	need ability to import rules
	StopRL does not stop immediately (old version did)
	help files are not accessible through gui

JavaRL improvements
	be faster on sets with many attributes
	statement at log window ("Run Complete") after loading and running the data
	on the start page for every RL run, create a check box to print plots of distributions of values for
		(a) all variables not ignored
		(b) all variables with information gain above a specific threshold
	in results file, include a line for "Maximum neg coverage" with its value
	in attribute dialogue, add a button to "Save" and "Exit", rather than using the X exist square to save and exit
	show number of missing values (Train/Test) - each variable : + frequency table of values
	flag cases with contradictory predictions à Show rules by target class
	names of train, validate & tests files on both rules and results files
	separate errors from No Prediction in the ***Predictions*** table
	RL parameters SHOULD NOT be reset when data files imported
	ignored attributes should have info gain of 0
	progress bars - current run and total
	be able to specify which attributes to chain on
	be able to input attribute types from file
	be able to input misclassification costs from file
	be able to input value hierarchies from file
	be able to specify min and max for continuous attributes without editing value hierarchy
	be able to input constraints from file
	be able to set interval breakpoints (without setting whole hierarchy)
	be able to handle multiple targets in the same run
	discretize continuous values more usefully
	use SQL databases for data
