Made minor changes - replaced typeToTree(Type) with inbuilt TypeTree(Type)
Removed dependency on Tuples for obtaining SetParameter objects
 - Implemented the parameters using Lists rather than Tuples. This removes the limit of 22 params that were being imposed earlier.
 - NOTE: We need to implement an object of SetParameter that can take parameters of the form List[Any] something along the lines of
SetParameter.SetSimpleProduct
Extended the macro to cases when only one column is selected from the database
Implemented consistent naming of interpolation class in typed-static-query API
