------------------------------------------------------------------------------
 ** Description
 
 This script combines groups of "show choice" options together as one large
 command. This allows you to create more than 4 choices by simply creating
 several "show choice" commands.
------------------------------------------------------------------------------
 ** Usage
 
 Add a show choice command.
 If you want more choices, add another one, and fill it out as usual.
 
 Note that you should only specify one cancel choice (if you specify more than
 one, then the last one is taken).
 
 For "branch" canceling, note that *all* cancel branches are executed.
 You should only have a cancel branch on the last set of choices
 
 You can disable automatic choice combining by enabling the "Manual Combine"
 option, which will require you to make this script call before the first
 show choice command
 
    combine_choices
    
 In order to combine choices together

 ** Terms of Use
 * Free to use in commercial/non-commercial projects
 * No real support. The script is provided as-is
 * Will do bug fixes, but no compatibility patches
 * Features may be requested but no guarantees, especially if it is non-trivial
 * Preserve this header
------------------------------------------------------------------------------
 ** Description
 
 This script provides extended control over choices.
 
 You can add "choice options" to each choice for further control over how
 they should appear, when they should appear, ...
 
------------------------------------------------------------------------------
 ** Usage
 
 To add choice option, use one of the methods defined in the reference section.
 For example, if you want to hide a choice 1 if actor 1's level is less than 5,
 you would write
   
   hide_choice(1, "$game_actors[1].level < 5")
   
------------------------------------------------------------------------------
 ** Reference
 
 The following options are available
 
 Method: disable_choice
 Effect: disables choice if condition is not met
 Usage:  Takes a string representing a boolean statement. For example,
         "$game_actors[1].level > 5" means that the condition will only be
         selectable if actor 1's level is greater than 5.
     
 Method: hide_choice
 Effect: hides choice if condition is met
 Usage:  Takes a string representing a boolean statement. For example,
         "$game_party.gold < 2000" means that the condition will not be shown
         if the party's gold is less than 2000
           
 Method: color_choice
 Effect: Very simple text color changing based on system colors
 Usage:  Takes an integer as the text color, based on the system colors.
         (eg: 2 is red by default). Check the "Window.png" file in your
         RTP folder to see the default colors
         
 Method: text_choice
 Effect: Sets the text of the choice to the custom text.
 Usage:  Takes a string that will replace whatever you place in the choice 
         editor. This allows you to exceed the 50-char limit.
