lightcouch: improve docs for View.query()

[srl295]

FYI lightcouch/LightCouch#60

…when include_docs=false (as in a reduce), the Class classOfT is applied to the entire row {key: …, value: …}, not just the value. This probably should be documented.

Thanks for the headsup @srl295 but we don't consume lightcouch from upstream and we've diverged quite a bit, we don't have a lightcouch style view query since 2.0.

The view code in java-cloudant 2.x is parameterized by <K> key and <V> value classes. So we always treat the values separately as type V.

We have a convenience method on a ViewRequest for retrieving a single reduce result:

• request.getSingleValue()

Otherwise the ViewResponse has values and rows also typed by <V>, see:

• response.getValues()
• response.getRows()
  • row.getValue()

If using include docs then the types of the row key and value are independent of the document type which is supplied as a class parameterized by <D> for example when calling:

• response.getDocsAs(Class<D> docType)
• row.getDocumentAsType(Class<D> docType)
