Title: Make the result stable.

JIRA: MADLIB-461 and MADLIB-449.
We use the MADLIB_SCHEMA.svec_to_string(svec) as the unique identifier for a svec, so that the results are stable now. According to the definition of support and confidence, the support and confidence of the generated association rules should be >= give values rather than >. We also fix that. Furthurmore, we remove the dead code of the implementation.
