Version 0.9

CHANGES:
- Added the choice of numeric vs. Boolean (true/false) fields
- Allowed users to set the upper and lower bounds for a field's values
- Added more specific error messages, particularly for input/output
problems

TO DO:
- Make a help file!
- Improve the GUI if possible (Make the Boolean fields more distinct
than just numeric fields with values limited to 0 and 1)
- Add a second, more accurate algorithm for 1-field configurations
(might need a different Team class for this).
