          Create CardLayout.  CardLayout shows 
          a single Component at a time, meaning
          it is not exactly practical to use it
          alone for a Layout.  This tutorial uses
          the BorderLayout to include a Panel in
          the Center Region, and within that Panel
          using a CardLayout.  A single card is 
          displayed at one time within a 
          ComponentContainer using CardLayout.

          CardLayout has four functions:
          next, previous, first, and last.

          ->next(CardContainerName): Causes 
          CardLayout to display the next card.
          ->previous(CardContainerName): Causes
          CardLayout to display the 
          previous card.
          ->first(CardContainerName): Causes
          CardLayout to display the
          first card.
          ->last(CardContainerName): Causes
          CardLayout to display the
          last card.

          These are most useful when combined with 
          Action, as shown at the top of 
          this Tutorial, to assign actions to the 
          Buttons or Components to allow the user 
          to cycle through the Card Layout and 
          view different ExampleCards.

          Note that CardContainerName is the name
          of the ComponentContainer which is using the
          CardLayout, while the begin/endEditCP
          is performed on the CardLayout itself.

            Minimum Size of the Component.
            Some Layouts will automatically
            resize Components; this prevents
            the Size from going below a
            certain value.

            Maximum Size of the Component.
            -setPreferredSize(Vec2f): Determine
            the Preferred Size of the Component.
            This is what the Component will
            be displayed at unless changed by
            another Component (such as a 
            Layout).
            -setToolTipText("Text"): Determine
            what text is displayed while
            Mouse is hovering above Component.
            The word Text will be displayed
            in this case.

            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
            Color for the text.
            -setRolloverTextColor(Color4f): Determine
            what the text Color will be when
            the Mouse Cursor is above the 
            Button.
            -setActiveTextColor(Color4f): Determine
            what the text Color will be when
            the Button is pressed (denoted by
            Active).
            -setAlignment(Vec2f):
            Determine the Vertical Alignment
            of the text.  The value is 
            in [0.0, 1.0].
