It adds documentation for the window functions and a couple of NULL tests. The documentation was largely based on the documentation in (the source of) Hive and Presto: * https://prestodb.io/docs/current/functions/window.html * https://cwiki.apache.org/confluence/display/Hive/LanguageManual+WindowingAndAnalytics I am not sure if we need to add the licenses of these two projects to the licenses directory. They are both under the ASL. srowen any thoughts? cc yhuai Author: Herman van Hovell <hvanhovell@questtec.nl> Closes #10402 from hvanhovell/SPARK-8641-docs.		2015-12-30 16:51:07 -08:00
