DS-1046 - API Counts - Implements the "count only" feature -- adding "countOnly=true"
as a parameter to an API call causes the system to return the count of the records
queried, without returning the records themselves.
pmd does not allow you to assign a value to a parameter passed into a method;
go figure.  I fixed this in ApiSchemaAdapter.java.
