*   This library allows you to enable or disable game saving. It works by showing 
*   a dialog instantly before a game is saved, causing the save to interrupt. There
*   are no known side effects.
*   _________________________________________________________________________
*   1. Installation
*   ¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
*   Copy the script to your map and save it (requires JassHelper *or* JNGP)
*   _________________________________________________________________________
*   2. API
*   ¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
*   This library provides one function
*
*       function SaveGameEnable takes boolean flag returns nothing
*       function IsSaveEnabled takes nothing returns boolean
*       function PreventSave takes player p, boolean flag returns nothing
