 * Introduction
 * ============================================================================
 *
 * Allows your actors' states to perform JavaScript evaluations as you walk on
 * the map... ♪ Every step you take ♪ ... I'm so sorry...
 *
 * ============================================================================
 * Usage
 * ============================================================================
 *
 * Add step effects to your states via the following notetag:
 *
 * State  >  Notebox  >  <ON STEP EFFECT>code</ON STEP EFFECT>
 *
 * It's as easy as that. If an actor in the game party has that state active,
 * you'll see that code's effect execute on each step of the map.
 *
 * Here are a couple of examples...
 *
 * <On Step Effect>
 * if (!($gameParty.steps() % 10))
 *   a.gainMp(Math.floor((Math.random()*200)-100)+1);
 * </On Step Effect>
 *
 * <on step effect>
 * if (user.isStateAffected(123))
 *   $gameTemp.reserveCommonEvent(45);
 * </on step effect>
 *
 * In the first example, the actor with the state —we'll call it "Mana Flux"—
 * gains or loses a random amount of mana (+/-100) for every ten steps they
 * take. The second example checks if another state is active on the actor as
 * well, and runs a Common Event if so.
 *
