 * Actors, Classes, Wapons, Armors, States, Enemies and Skills Notetags:
 * ------------------------------------------------------------------------------
 *  
 *  <passive state: id>
 *   The state will be always active on objects with this tag.
 *     id : state ID
 *
 * ---------------
 *
 *  <passive state: id, param check x>
 *  <passive state: id, param check x%>
 *   The state will be active when the param checked match the value x.
 *     id    : state id
 *     param : param name (maxhp, maxmp, maxtp, hp, mp, tp, atk, def, mat...)
 *     check : check type (higher, lower, equal or different)
 *	   x     : value checked (if param is hp, mp or tp, can be a % value)
 *
 * ---------------
 *
 *  <passive state: id, state check x>
 *   The state will be active when the stated ID x match checked condition.
 *     id    : stated ID (stated ativated)
 *     check : check type (added or removed)
 *	   X     : stated ID (state checked)
 *
 * ---------------
 *
 *  <passive state: id, switch check x>
 *   The state will be active when the switch ID x match checked condition.
 *     id    : state ID
 *     check : check type (on or off)
 *	   x     : switch ID
 *
 * ---------------
 *
 *  <custom passive state: id>
 *   result = code
 *  </custom passive state>
 *  Can use a code to make the skill check. The code must return true or false.
 *  Require coding knowledge.
 *     id   : state ID
 *     code : js code
 *
 * ------------------------------------------------------------------------------
 * Additional Information:
 * ------------------------------------------------------------------------------
 * 
 *  The code uses the same values as the damage formula, so you can use "a" for
 *  the user, "b" for the target, "v[x]" for variable and "item" for the item
 *  object. The 'result' must return a true/false value.
 *
 * ------------------------------------------------------------------------------
 * Example Notetags:
 * ------------------------------------------------------------------------------
 *
 *   <passive state: 4, hp lower 50%>
 *
 * ---------------
 *
 *   <passive state: 5, mp equal 0>
 *
 * ---------------
 *
 *   <passive state: 6, sate added 3>
 *
 * ---------------
 *
 *   <passive state: 7, switch on 5>
 *
 * ---------------
 *
 *   <custom passive state: 8>
 *    result = $gameVariables.value(2) < 10;
 *   </custom passive state>
 *
 * ---------------
 *
 *   <custom passive state: 9>
 *    result = $gameSwitches.value(1) || $gameSwitches.value(2);
 *   </custom passive state>

 * 必要プラグイン
 * ===========================================================================
 *
 * このプラグインを使用するには、下記のプラグインが必要です。
 * - VE_BasicModule
 *
 *
 * ---------------------------------------------------------------------------
 * アクター、職業、武器、防具、ステート、敵、スキルのメモタグ
 * ---------------------------------------------------------------------------
 *
 *  <passive state: id>
 *   このステートは、このタグを持つオブジェクトに対して常に有効化されます。
 *     id : ステートID
 *
 * ---------------
 *
 *  <passive state: id, param check x>
 *  <passive state: id, param check x%>
 *   能力が条件に一致した場合、ステートが解除されます。
 *     id    : ステートID
 *     param : 能力名 (maxhp, maxmp, maxtp, hp, mp, tp, atk, def, mat...)
 *     check : 確認型 より大きい:higher / より小さい:lower / 等しい:equal /
 *                    等しくない:different
 *     x     : 確認値 param が hp, mp ,tp の場合、%が使えます。
 *
 * ---------------
 *
 *  <passive state: id, state check x>
 *   ステートxが条件に一致した場合、ステートが解除されます。
 *     id    : ステートID (有効化ステート)
 *     check : 確認型 付加:added / 解除:removed
 *     x     : ステートID (確認されるステート)
 *
 * ---------------
 *
 *  <passive state: id, switch check x>
 *   スイッチIDxが条件に一致した場合、ステートが解除されます。
 *     id    : ステートID
 *     check : 確認型 on / off
 *     x     : スイッチID
 *
 * ---------------
 *
 *  <custom passive state: id>
 *   result = code
 *  </custom passive state>
 *  コードを使って確認を行うことができます。
 *  コードはtrueかfalseを返す必要があります。
 *  コーディングの知識が必要です。
 *     id   : ステートID
 *     code : JavaScriptコード
 *
 *
 * ---------------------------------------------------------------------------
 * 追加情報
 * ---------------------------------------------------------------------------
 *
 * コードではダメージ式と同じ値を使っているので、使用者には'a'、対象には'b'、
 * 変数には'v[x]'、アイテムオブジェクトには'item'を使うことができます。
 * 'result'は true/false の値を返す必要があります。
 *
