 * @target MZ
 * @plugindesc It provides some functions to make your game's camera smoother and more functional.

 * Introduction:
 *   This plugin generates a delay effect in the movement of the camera until 
 *   it stabilizes in focus. Creating a smooth effect!
 *
 * Usage:
 *   I created a lot of commands to make this plugin as user friendly as I could! 
 *   See each of them and their description to understand how to use it.
