 * @plugindesc A plugin that tracks six custom attributes per actor.
 *
 * @help This plugin allows you to track six custom attributes per actor.
 * You can access these attributes using script calls or by using them in
 * formulas in the database.
 *
 * Usage:
 * - Add the following notetag to the actor notebox:
 *   <customAttributes: attr1, attr2, attr3, attr4, attr5, attr6>
 *   Replace attr1-6 with the names of your custom attributes.
 *
 * - To access an actor's custom attribute, use the following script call:
 *   $gameActors.actor(actorId).customAttributes[attrName]
 *   Replace actorId with the ID of the actor and attrName with the name of the
 *   custom attribute you want to access.
 *
 * - To set an actor's custom attribute, use the following script call:
 *   $gameActors.actor(actorId).setCustomAttribute(attrName, value)
 *   Replace actorId with the ID of the actor, attrName with the name of the
 *   custom attribute you want to set, and value with the new value.
 *
 * Example:
 * - Add the following notetag to the actor notebox:
 *   <customAttributes: strength, agility, intelligence, wisdom, charisma, luck>
 *
 * - To access an actor's strength attribute, use the following script call:
 *   $gameActors.actor(1).customAttributes.strength
 *
 * - To set an actor's agility attribute to 20, use the following script call:
 *   $gameActors.actor(2).setCustomAttribute('agility', 20)
