API

   setDates([dates]:tuple);
   //Set  dates to DatePicker
   //dates accept <string> and <Date>

   setLanguage(language:any);
   //set DatePicker's language

   setData(callback)
   //set data to DatePicker
   //more detail see [USAGE]

   setDisabled({
        days?:Array<number>[5],
        dates?:Array<string|Date>,
        from?:<Date|string>,
        to?:<Date|string>
    })
   //Set disabled dates to DataPicker
   //dates =>dates accept <string> and <Date>,  all dates in [dates] will be disabled
   //days => days accept number of [0~6],   all days in [days] will be disabled
   //from => from accept <string> or <Date>, all dates after [from] date will be disabled,
   //        eg: from = 2018-3-31 => disabled from 2018-4-1  
   //to   => to accept <string> or <Date> all dates before [to] date will be disabled,
   //        eg: to =2018-3-4 => all dates before 2018-3-5 will be disabled

   parse(formattedDate:string,dateFormat:string)
   //Transform date string into date object,return Date object
   //eg: formattedDate ='2018-3-4',format='YYYY-M-D" =>  new Date(2018,2,4)

   format(date:Date,format:string)
   //Transform date object into string,return string  
   //eg: date =new Date(),format='YYYY-MM-DD' => 2018-03-04

   on(event:string,fn:Function)
   //Event listener
   //eg: datePicker.on("event",(result)=>{
                //your logic
   //    })
