> Support the IntervalType in window range frames, as mentioned in the conclusion of the databricks blog [post|https://databricks.com/blog/2015/07/15/introducing-window-functions-in-spark-sql.html] on window functions.
> This actualy requires us to support Literals instead of Integer constants in Range Frames. The following things will have to be modified:
> * org.apache.spark.sql.hive.HiveQl
> * org.apache.spark.sql.catalyst.expressions.SpecifiedWindowFrame
> * org.apache.spark.sql.execution.Window
> * org.apache.spark.sql.expressions.Window
