Couchbase Lite Tombstones documentation

Tombstones are perceived in CB Lite as an empty bodied documents with an ID and not content.
it isn't mentioned on anywhere in the lite documentation page but as an afterthought here-> https://docs.couchbase.com/sync-gateway/2.1/managing-tombstones.html

Usually Lite and Mobile developers would overlook it, as there is not way to know that these are related to Lite, unless you specifically read the documentation about tombstones of Sync Gateway.

It would be good to add a section to the Lite documentation, explaining tombstones, plus an example of how to purge them.

*Opened about the C# page, but it applies for all platforms
