 *      Suppose a battler has n action slots(that battler can input n actions 
 *      in a single turn), and suppose that battler has inputted n actions,   
 *      each needing xi turns to be charged, where 1 <= i <= n, then that     
 *      battler will behave as follows:                                       
 *      1. At turn y, that battler has inputted the aforementioned n actions  
 *      2. At turn y + x1, that battler will execute the 1st inputted action  
 *      3. At turn y + x1 + x2, that battler will execute the 2nd inputted    
 *         action                                                             
 *      4. At turn y + x1 + x2 + x3, that battler will execute the 3rd        
 *         inputted action                                                    
 *      5. At turn y + x1 + x2 + x3 + ... + xi, where 1 <= i <= n, that       
 *         battler will execute the ith action                                
 *      6. At turn y + x1 + x2 + x3 + ... + xn, that battler will execute the 
 *         nth action                                                         
 *      7. At turn y + x1 + x2 + x3 + ... + xn + 1, that battler will become  
 *         able to input actions again                                        
 *      If the ith action that's not executed yet is the 1st one needing      
 *      charging, the battler speed will only take the first (i - 1)th        
 *      actions' speeds into account                                          
 *      Item charging's ignored by forced actions

 *
 * @param isEnabled
 * @desc Sets whether this plugin will be enabled
 *       It'll be stored as a boolean, and will be regarded as true if and only
 *       if it's true
 *       Don't change this during the same battle unless you really know what
 *       you're truly foing
 *       E.g.: Setting isEnabled as false will disable this plugin
 * @default true
 *
 * @param textColor
 * @desc Sets the text color of the text showing the number of turns needed to
 *       charge the skill/item on the skill/item window
 *       It'll be stored as a Number
 *       Don't change this when it's shown to ensure proper text displays
 *       E.g.: Setting textColor as 31 will set the text color of the text
 *             showing the number of turns needed to charge the skill/item on
 *             the skill/item window as 31
 * @default 30
 *
 * @help
 * The skill/item window charging turn display can be problematic if the
 * number of turn's 1000 or above
 * The default plugin file name is DoubleX RMMV Item Charge v100a
 * If you want to change that, you must edit the value of
 * DoubleX_RMMV.Item_Charge_File, which must be done via opening this plugin
 * js file directly
