This fixes the encoder so that it will encode the response correctly to

updated helper program so users can now start with a .in.csv file, and a .ifql file, and
generate output. program asks user to verify output before writing. Also refactored the
location of test files from query_test to querytest and put helper functions in new file
querytest/execute.go.
