 *
 * @help In order to use this plugin, you must first decide which BGM and BGS you want
 * to apply to players' parties or enemy troupes.
 * Pick the name of the BGM or BGS and put it's file name
 * in the parameters section.
 * (No need for " marks here.)
 * You can then adjust the volume, pitch and pan levels to your liking.
 * Finally, you can set the percentage of HP that will be considered
 * critical for your game.
 * It defaults to 25%.  This means that once the party or troupe's total hp
 * reaches 25% of it's total Max HP, the music/sounds will begin.
 * (If the hp goes above the critical point, the music/sounds will revert
 * to what they were before.)
 *
 * Note that you must keep the PLugin's file name set as MalCritBGMBGSChanger.js
 *
 * Script Calls:
 * There are several Script calls that can be used with this plugin.
 * Note that these calls make TEMPORARY changes to the plugin and will reset to
 * default upon loading up a new save.
 *
 * $gameSystem.changePartyCritBGM(name);
 * This call will change the BGM used when the party becomes critical.
 * (Use quote marks " around the name.)
 *
 * $gameSystem.changeEnemyCritBGM(name);
 * This call will change the BGM used when the enemy troupe becomes critical.
 * (Use quote marks " around the name.)
 *
 * $gameSystem.changePartyCritBGS(name);
 * This call will change the BGS used when the party becomes critical.
 * (Use quote marks " around the name.)
 *
 * $gameSystem.changeEnemyCritBGS(name);
 * This call will change the BGS used when the enemy troupe becomes critical.
 * (Use quote marks " around the name.)
 *
 * $gameSystem.changeCritBGMVol(number);
 * This call will change the volume of all BGM changes, party or enemy, when
 * they become critical.
 * (Keep the number within the range given for the parameter section.)
 *
 * $gameSystem.changeCritBGMPitch(number);
 * This call will change the pitch of all BGM changes, party or enemy, when
 * they become critical.
 * (Keep the number within the range given for the parameter section.)
 *
 * $gameSystem.changeCritBGMPan(number);
 * This call will change the pan level of all BGM changes, party or enemy, when
 * they become critical.
 * (Keep the number within the range given for the parameter section.)
 *
 * $gameSystem.changeCritBGSVol(number);
 * This call will change the volume of all BGS changes, party or enemy, when
 * they become critical.
 * (Keep the number within the range given for the parameter section.)
 *
 * $gameSystem.changeCritBGSPitch(number);
 * This call will change the pitch of all BGS changes, party or enemy, when
 * they become critical.
 * (Keep the number within the range given for the parameter section.)
 *
 * $gameSystem.changeCritBGSPan(number);
 * This call will change the pan level of all BGS changes, party or enemy,
 * when they become critical.
 * (Keep the number within the range given for the parameter section.)
 * *
 * $gameSystem.disableCritSounds();
 * This call will disable ALL crit BGM and BGS for both party and troupe.
 *
 * $gameSystem.enableCritSounds();
 * This call turns the BGM and BGS changes back on.
