#------------------------------------------------------------------------------#
#  A HUD that displays information that might be useful for an RPG with a lot of
#  exploring. Can toggle it on or off when needed with a button. The info
#  displayed is the actor leading the party, so it works well with a script
#  such as Tsukihime's Rotate Formation to switch the lead actor with the press
#  of a button.
