Ventwig's Simple Face HUD

#============================================================================
#Simple Face HUD
#By Ventwig
#Version 1.31 - April 14 2012
#For RPGMaker VX Ace
#============================================================================
# This is my first script :)
# Since I'm new, I know stuff in this script can be simplified, but oh well
# I decided to try scripting and learned through some videos and the help
# of amazing members on the forums :D
# Also, thanks to XAIL's Simple Gold HUD, I was able to learn off of
# it. For the stuff to show on the map.
#=============================================================================
# Description:
# This piece of code let's you show the player's party (Max 4, Min 1) on the
# top of the screen. It shows the faces of the current party members.
# Only the first four in the party, which is good because there's usually only
# 4 active at a time. You can choose to display names, and choose which
# gauges to be shown, or even draw the sprite graphic!
# Anyways, it centers the faces, too :)
#==============================================================================
# Compatability:
#  alias-es Scene_Map
#  Works with Neo Gauge Ultimate Ace
#===============================================================================
# Instructions: Put in materials, above main. Almost Plug and Play
# Put above Neo Gauge Ultimate Ace if used
#==============================================================================
# Please give Credit to Ventwig if you would like to use one of my scripts
# in a NON-COMMERCIAL project.
# Please ask for permission if you would like to use it in a commercial game.
# You may not re-distribute any of my scripts or claim as your own.
# You may not release edits without permission, combatability patches are okay.
