Merge pull request #199 from phillipCouto/support_1.2

Added 1.2.x to intergration testing.
Alternative attempt to expose query binding meta data to the application
Implemented a test that uses the query info in conjunction with relfection to build out a more realistic use case
Added Bind() to Batch interface
Batches are not supported so well in Cassandra 1.x
Removed duplicate *Iter instance
Minor refactoring to make it clearer to see what is going on with this reflection
Added behavioral test to validate whether *queryInfo should indeed include a non-empty return value args
The binding callback can now return an error, which will in turn bubble up to the app
Added godocs
Read both the query argument and the result metadata
Only read result column meta data for v2 of the protocol
