the N1QL operator 'OBJECT' is not documented

Need to document OBJECT operator. More details in section "ARRAY, FIRST, and OBJECT" at https://github.com/couchbase/query/blob/master/docs/n1ql-select.md

Example at this forum disc: Visit Topic

It should be documented at: https://developer.couchbase.com/documentation/server/4.6/n1ql/n1ql-language-reference/collectionops.html
