      Description

      Percentile scale is often used in feature scale.
      In my project, I need to use this scaler.
      Compared to MinMaxScaler, PercentileScaler will not produce unstable result due to anomaly large value.

      About percentile scale, refer to https://en.wikipedia.org/wiki/Percentile_rank
