 * ============================================================================
 * Introduction
 * ============================================================================
 *
 * A feature that was removed from RPG Maker 2000 and RPG Maker 2003 was the
 * Stop Event Movement event. This event prevented events from automatically
 * moving by themselves, so they don't intrude on cutscenes, catch up to the
 * player during messages, etc.
 *
 * This plugin recreates that feature in the form of a plugin command for you
 * to use with RPG Maker MV!
 *
 * ============================================================================
 * Plugin Commands
 * ============================================================================
 *
 * You can use the following plugin commands to produce the following effects:
 *
 * Plugin Command
 *
 *   StopEventMovement
 *   Stops events from automatically moving by themselves. You can still move
 *   events through movement routes set by your active event.
 *
 *   AllowEventMovement
 *   Allows events to move automatically by themselves again. If you have any
 *   of the plugin parameters disabling events from moving during either events
 *   or messages, this will not bypass it.
 *
 *   StopPlayerMovement
 *   Stops player from being able to move via input. You can still move the
 *   player through movement routes set by your active event.
 *
 *   AllowPlayerMovement
 *   Allows player to move again via input.
 *
 * ============================================================================
 * Changelog
 * ============================================================================
 *
 * Version 1.02:
 * - Updated for RPG Maker MV version 1.5.0.
 *
 * Version 1.01:
 * - Optimized updating performance to reduce lag on maps with many events.
 *
 * Version 1.00:
 * - Finished Plugin!
