Review Comment:
You are saying use `UNIVOT` instead of `MELT` in this line only? Or use
`unpivot` wherever this PR mentions `melt`? API, catalyst, docu?
In the latter case: should we at least have `Dataset.melt` as an alias for
`Dataset.unpivot`, given in Pandas and PySpark Pandas the method *is called*
`melt`?
