 * Introduction
 * ============================================================================
 *
 * 这个插件需要YEP_BattleEngineCore战斗引擎核心，确保放在这个插件下面
 * 
 *
 * 这个插件可以在敌方被击中或者选择时显示血量，你也可以设置队员的
 * 血量显示。你可以调整血量显示的参数。
 *
 * 敌方默认不需要先击倒在显示血量。这个可以通过参数设定。但是，在编
 * 辑器战斗测试时，血量会一直显示，除非敌方隐藏。
 *
 * ============================================================================
 * Notetags
 * ============================================================================
 *
 * Class and Enemy Notetags:
 *   <Hide HP Gauge>
 *   隐藏血量
 *   This HP gauge will always be hidden if this notetag is present.
 *
 *   <Show HP Gauge>
 *   显示血量
 *   This HP gauge will always be shown if this notetag is present while the
 *   target is selected or taking damage.
 *
 *   <HP Gauge Width: x>
 *   血量槽宽度，如果宽度小于最小宽度，将会取最小宽度
 *   This will set the battler's HP Gauge width to x pixels. However, if this
 *   width is less than the minimum width, minimum width will take priority.
 *
 *   <HP Gauge Height: x>
 *   血量槽高度
 *   This set's the HP Gauge height to x pixels.
 *
 *   <HP Gauge Back Color: x>
 *   血量槽背景颜色
 *   This changes the HP Gauge's back color to x text color.
 *
 *   <HP Gauge Color 1: x>
 *   血量槽颜色1
 *   This changes the HP Gauge's color 1 to x text color.
 *
 *   <HP Gauge Color 2: x>
 *   血量槽颜色2
 *   This changes the HP Gauge's color 2 to x text color.
 *
