/**
 * <p>Title: JModel User Classes Panel</p>
 * <p>Description: Panel used to edit user classes properties. Extends JSIM ClassesPanel.
 * In some points it is a bit tricky, as original ClassesPanel was not meant to be extended.
 * I preferred not to change ClassesPanel source code, nor copy and modificate it as
 * at the time of writing it was in early development stage and I didn't want to collide
 * with the author.</p>
