USB Composite HID Keyboard Mouse Device

This example application turns the evaluation board into a composite USB
keyboard and mouse example using the Human Interface Device class.  The
color LCD displays a blank area which acts as a mouse touchpad.  The button
on the bottom of the screen acts as a toggle between keyboard and mouse
mode.  Pressing it toggles the screen to keyboard mode and allows keys
to be sent to the USB host.  The board status LED is used to indicate the
current Caps Lock state and is updated in response to pressing the ``Caps''
key on the virtual keyboard or any other keyboard attached to the same USB
host system.
