 * How To Use
 * ============================================================================
 *
 * This plugin causes all battles (random or event) to not cause a game over
 * event after a loss, by default. No commands or parameters needed for the
 * basic function, they're just for more control.
 *
 * The plugin is designed for those who wish to allow the player to lose a
 * random encounter, just like an event battle.
 *
 * The first parameter also allows you to run a common event after a loss, or use
 * a value of 0 to have no common event run.
 *
 * The second parameter is a switch for if you want to control the default
 * behavior. Off for no game over default, on for normal RPG Maker behavior.
 * Use 0 if you don't want to use a switch, so it always allow losses.
 *
 * The plugin commands are for when you want to change whether or not a game
 * over will occur upon a loss in the middle of a battle, or to make certain
 * troops/encounters (like bosses) cause a game over if lost to.
 *
 * Plugin Command:
 *   CanLose false          # Makes it so a loss causes the game over event
 *   CanLose true           # Makes it so a loss does not cause a game over
 *   CanLose eventID 2      # Sets the event ID to 2, and prints in the console
 *   CanLose checkSwitch    # Returns ID of the switch & prints it in the console
 *
 * ============================================================================
 * Terms Of Use
 * ============================================================================
 * Free to use and modify for commercial and noncommercial games, with credit.
