I used Spark and HoltWinter Method for predicting a timeSeries. I don't have the write access for the repository. I can merge the conflicts and extend the function at  [HoltWinter](https://github.com/josepablocam/spark-timeseries/blob/holtwinters/src/main/scala/com/cloudera/sparkts/HoltWinters.scala) to additive and multiplicative variants. I used the same logic in [HoltWinter.R](https://github.com/wch/r-source/blob/trunk/src/library/stats/R/HoltWinters.R) does this cause any issue in open source contribution ?"}}
