Docs: Inconsistent user key usage between text and graphics

Section: http://docs.couchbase.com/couchbase-devguide-2.5/#using-reference-documents-for-lookups
Area: First paragraph and then an issue between the text and the graphics
Issues: (1) The string 'can still provide better performance if you are the lookup frequently’ needs a change. The word ‘are’ is not correct. Not sure what it should be though. (2) Change 'associated with the main the document’ to 'associated with the main document’ (remove the second ‘the’). (3) The later description of the code does not appear to match the code. We talk about user::count, but then we have a uid value of 12f1, from the UUID call in the code. The screenshots look right, but there is a text reference to user::101 in the string 'key for the user record user::101. The first document’. This does not appear to be accurate since our key is user:12f1. We also show pointers to => 101, which are not valid. I personally like the user::101 syntax as an example, because it shows use of a counter instead of a somewhat random value from the UUID call. That’s what is shown on couchbasemodels.com. Whichever approach we prefer to show, it just needs to be consistent between the code snippets and the graphics.
