#------------------------------------------------------------------------------
# * Description :
#
#   This is a mix-in module for windows subclassing designed to 'enhance' the
#   arrow-key movement system used to select the item by creating warping.
#   That is, if you are at the bottom and press down you will go up to the top
#   in the next column. Like-wise for down, left and right.
#------------------------------------------------------------------------------
# * Instructions :
#
#   Place the script anywhere above Main.
#   To give a subclass of Window_Selectable let it include the module
#
#   If you for example wanted to apply the module to Window_Item you should
#   write this code: (Must be below the original Window_Item
# ------------------------------------------
#   class Window_Item < Window_Selectable
#     include Window_Selectable_Type_2
#   end
# ------------------------------------------
#
#   Here is a version for Window_Skill. You get the idea.
# ------------------------------------------
#   class Window_Skill < Window_Selectable
#     include Window_Selectable_Type_2
#   end
# ------------------------------------------
#
#   Note: Don't include this module in Window_Selectable ~
#         May cause issues with Windows where the update method is used
