/**
 * This guy is a formula editor--kind of like a line editor but
 * you can do formulas.  If you construct it with restricted
 * set to true, it prevents you from typing things it doesn't know
 * how to evaluate (like matrices, greek, integrals, etc.)
 * If you want to use your own evaluation, but want to have
 * the typing restrictions, you can use uglyForm() on a restricted formula
 * to get a c-style expression and setExtraChars() to allow characters
 * beyond the default allowed in restricted mode.
 *
 * Features of KFormulaEdit include infinite undo/redo, cut/copy/paste,
 * and you can enter almost anything KFormula can display (I think).
 * To save a formula, use text(), save the returned string, and when
 * loading use setText(QString) with the saved string.
 *
 * Keyboard shortcuts are availiable, but it's probably easier to
 * use a KFormulaToolBar (which see).
 * @short A WYSIWYG formula editor widget.
