/*:
 * @plugindesc Allows you to cause the player to start/stop spinning in place (even while walking). See "help"...
 * @author Ben Hendel-Doying
 * @help
 * To cause the player to start spinning, run this script (either via an event,
 * or your own JS script)
 *
 *   $gamePlayer.startSpinning(10);
 *
 * You can replace the 10 with any number from 1 to 60. A higher number means a
 * greater speed of rotation. (Technically, this is the number of 90 degree
 * turns per second; there are 60 frames per second, so...)
 *
 * To STOP the player spinning, call:
 *
 *   $gamePlayer.stopSpinning();
 *
 * You may also start the player spinning in such a way that they will
 * automatically stop spinning after some number of frames:
 *
 * $gamePlayer.startSpinning(20, 60);
 *
 * The above will cause the player to rotate 20 times per second; they will
 * stop spinning after 60 frames (1 second).
