-setToolTipText("Text"): Determine
what text is displayed while

Functions specfic to Button:
-setText("DesiredText"): Determine
the Button's text. It will read
DesiredText in this case.
-setFont(FontName): Determine the
Font to be used on the Button.
-setTextColor(Color4f): Determine the

what the text Color will be when
the Mouse Cursor is above the
