 * Introduction
 * ============================================================================
 *
 * 这个插件需要YEP_EquipCore.js，请把它放在YEP_EquipCore.js下面
 *
 * 设置装备限制，例如等级限制，状态限制。这个插件可以提供单独的装备限制窗
 * 口给玩家，告诉他们需要什么
 *
 * ============================================================================
 * Notetags
 * ============================================================================
 *
 * 你可以使用标签来设置限制。
 *
 * Weapon and Armor Notetags:
 *
 *   <Equip Requirement>
 *    requirement
 *    requirement
 *   </Equip Requirement>
 *   -主要需要放在这些标签里面。你可以设置多个需求.
 *   You can have a multitude of requirements for your weapons/armors. Replace
 *   'requirement' with any of the following below:
 *
 * Weapon and Armor Requiprements:
 *
 *   param > x
 *   param >= x
 *   param === x
 *   param <= x
 *   param < x
 *   设置等级，状态等等限制。这些数值指的是基础数值而不是最后叠加数值
 *   This will make the piece of equipment require the
 *   actor's base parameter to be greater than (>), greater than or equal to
 *   (>=), equal to (===), less than or equal to (<=), or less than (<). This
 *   is NOT the value for the total parameter, only the base parameter. The
 *   base parameter is calculated by the user's class parameter value, any
 *   bonuses received by equipment and/or permanent stat increases.
 *
 *   class: x
 *   class: name
 *   - 设置需要职业 x.
 *   If 'name' is used, priority will be given to the class with the highest ID
 *   in the database. Insert multiple of these requirements to add more
 *   classes. Having multiple classes will mean that the actor can be any of
 *   those classes to be able to equip the gear.
 *
 *   skill: x
 *   skill: name
 *   - 设置需求技能
 *   skill x. If 'name' is used, priority will be given to the skill with the
 *   highest ID in the database. Insert multiple of these requirements to add
 *   more skills. Having multiple skills means the actor must have learned ALL
 *   of the skills to be able to equip the gear.
 *   玩家必须通过学习习得这个技能。如果通过特性赋予，则不会生效
 *
 *   switch: x
 *   - 需要开关x打开. If it isn't, the piece of equipment
 *   cannot be worn. Insert multiple of these to add more switches that are
 *   are required to be on.
 *
 *   unique only
 *   - This will make the piece of equipment to be "unique", rendering the
 *   actor to be unable to wear more than 1 of its kind.
 *
 * ============================================================================
 * Lunatic Mode - Custom Equip Requirement Conditions
 * ============================================================================
 *
 * For those with JavaScript proficiency, you can use these notetags to give
 * certain pieces of equipment a special requirement before it can be equipped.
 *
 * Weapon and Armor Notetags:
 *
 *   <Custom Equip Requirement Condition>
 *    if (user.name() === 'Harold') {
 *      condition = true;
 *    } else {
 *      condition = false;
 *    }
 *   </Custom Equip Requirement Condition>
 *   The 'condition' variable will determine whether or not the piece of
 *   equipment can be worn by the user. If 'condition' returns 'true', then the
 *   piece of equipment can be worn. If 'condition' returns 'false', then the
 *   piece of equipment can't be worn.
 *
 * ============================================================================
 * Lunatic Mode - Custom Equip Requirement Text
 * ============================================================================
 *
 * For those with JavaScript proficiency, you can use these notetags to alter
 * the text displayed in the Requirement Window.
 *
 * Weapon and Armor Notetags:
 *
 *   <Custom Equip Requirement Text>
 *    text = user.name() + ' has used this sword since young!\n';
 *    text += 'This is another line for the text!'
 *   </Custom Equip Requirement Text>
 *   For those who would like to write custom text for the Requirement Window,
 *   you can use this notetag. Text codes are allowed here. Use \n for line
 *   breaks. If you plan on using text codes, \i[4] would appear as \\i[4].
 *   Whatever value the 'text' variable has at the end will determine the text
 *   that will be displayed.
 *
 * ============================================================================
 * Changelog
 * ============================================================================
 *
 * Version 1.06:
 * - Lunatic Mode fail safes added.
 *
 * Version 1.05a:
 * - Fixed a bug that caused unremovable items to be removed.
 * - Added anti-crash for non-existent actors.
 *
 * Version 1.04:
 * - Fixed a bug that caused stat comparisons to remain after cancel.
 *
 * Version 1.03:
 * - Notetags now allows spaces (whitespace) to be before the requirements.
 *
 * Version 1.02:
 * - Fixed a bug where Optimize was able to bypass equip requirements.
 *
 * Version 1.01:
 * - Updated for RPG Maker MV version 1.1.0.
 *
 * Version 1.00:
 * - Finished Plugin!
