   1. Benefit
       - This PR makes it possible to calculate weighted percentile (linear 
interpolation of first argument), directly.
       - It's possible to accept frequency argument of double type
       - **(WIP)** It's currently not compatible with existing percentile 
function which used only integer as frequency 
   2. Work In Progress
       - Its own unittest is not yet implemented
   3. I have executed `dev/scalastyle`
   4. Other db engines don't seem to provide percentile function with 
**frequency**, unlike percentile aggregate function of catalyst package in Spark
