 * @author Lyson
 * @plugindesc Allows events to flip a self switch when a
 * player is in range.
 *
 * @param Self Switch
 * @desc The self switch to flip when the player is in range.
 * A, B, C, or D
 * @default D
 *
 * @help
 * =============================================================================
 * What does it do?
 * =============================================================================
 *
 * This plugin activates a self switch when a player is in a certain proximity
 * of an event. It uses a notetag in the note of the event to set the proximity.
 *
 * =============================================================================
 * Usage
 * =============================================================================
 *
 * In the plugin parameters, set the self switch to be triggered on the event
 * when a player enters the range. Options are A, B, C, and D. Default is D.
 *
 * Event tags provide 2 way functionality, they will turn off the switch when
 * the player leaves the event's range.
 *
 * Comment tags only provide 1 way switching, they will NOT turn off the Self
 * Switch when the player leaves the event's range.
 *
 * -----------------------------------------------------------------------------
 * Notetags
 * -----------------------------------------------------------------------------
 *
 * These notetags go in the note box for the event or in a comment on an event
 * page.
 *
 *    <Sensor: x>
 *
 * Where x is the number of tiles away that the selfswitch will be triggered.
 *
