 * @plugindesc Turns on switches when a battle ends according to battle results
 * @author Shaz
 *
 * @param Battle Won Switch
 * @desc Switch ID to turn on if battle is won
 * @default 0
 *
 * @param Battle Lost Switch
 * @desc Switch ID to turn on if battle is lost
 * @default 0
 *
 * @param Battle Escaped Switch
 * @desc Switch ID to turn on if player escapes from battle
 * @default 0
 *
 * @param Battle Abort Switch
 * @desc Switch ID to turn on if battle is aborted
 * @default 0
 *
 * @help This plugin does not provide plugin commands.
 *
 * When calling a Battle from an event command, you can set up actions to
 * happen after the battle is over, depending on whether the party won, lost
 * or escaped.
 *
 * This can't be done by default with random encounters set up on a map,
 * as there is no calling event.
 *
 * This plugin allows you to turn on a switch when a battle is won, lost,
 * or escaped, which you can then use to control map events or common events.
 *
 * Use 0 as a parameter to indicate not to turn on a switch for that
 * condition.  All of these switches will be turned off at the start
 * of battle.
