/*:
 * @plugindesc [v1.00] This plugin allows you to define different names for
 * classes based on level.
 * @author John Clifford/Trihan
 *
 * @help
 * ============================================================================
 * Introduction
 * ============================================================================
 *
 * This plugin provides the developer the facility to have actor classes
 * automatically change their names as the actor possessing that class hits
 * defined level milestones.
 *
 * ============================================================================
 * Notetags
 * ============================================================================
 *
 * Use the following notetag in the notebox of your classes (indentation is
 * purely for ease of reading and is not necessary in the note itself):
 *
 * <NameList>
 *   level:name
 *   level2:name2
 *   level3:name3
 * </NameList>
 *
 * Example (in the 'Black Mage' class):
 *
 * <NameList>
 *   5:Black Magus
 *   10:Black Sorcerer
 *   15:Sorcerer Supreme
 * </NameList>
 *
 * You can define as many level-name pairs as you wish. They should be in level
 * order; ordering them otherwise may cause the wrong name to be shown. The
 * original name of the class will be used at first unless you define a level 1
 * pairing.
 *
 * As soon as the actor attains the level defined by a line, that is the name
 * that will be displayed for their class until the next one is reached.
