Mongoose Count & Find is a Mongoose plugin that provides a method,
countAndFind(), for performing a count and a find at the same time. The
point is to provide a count in addition to a set of matching documents. The
important thing to note is that as with countAndfind() behaves just like
find() you can use limit() and skip(), but these will only affect the
set of matching documents fetched, not the count. This makes for simpler code
when dealing with paginated results via REST.
countAndFind() has exactly the same signature and behavior as the built in
find() method with one exception. The countAndFind() calls back with the
total count of documents matching the query conditions in addition to the
expected array of documents.
