Pulled "Magic Numbers" out of MainGUI.java and made them final/constant variables
Fixed Error in Code:
btnEnterRecordActionPerformed throws "Exception in thread "AWT-EventQueue-0" java.lang.ArrayIndexOutOfBoundsException: 10"

Fixed by making the if statement >= 10 (or MAX_RECS) instead of just > 10
Lab 3 Complete. Encapsulated necessary Methods and implemented them properly. 
Sort Function not working properly (not sure if it ever was)
