Class that allows the developer to construct and execute a query to the Federal Reserve Bank of St. Louis' FRED web services.
Note that this class is not thread-safe and cannot be used as a member -level property -- if this is required, use the {@link com.coherentlogic.fred.client.core.builders#RequestBuilderFactory QueryBuilderFactory} class.
In order to facilitate method-chaining each setter method returns a reference to this object.
For examples, refer to the {@link com.coherentlogic.fred.client.core.builders#QueryBuilderTest QueryBuilderTest} class.
