Rewrite SQL++ functions. -Maps SQL function names to internal names. -Allows SQL++ builtin functions to be case-insensitive. -Rewrites SQL-92 global aggregates. -Refactors SQL++ AST visitors. -Cleans up semantics of COLL_AGG and SQL-92 AGG.
Run ExecutionTest w/integration test framework I changed the default local.xml to use 2 NCs with 2 partitions each like AsterixHyracksIntegrationUtil so that the results will match despite using simple string compare to determine correctness.
There is also one test in particular (big-object-join) that I had to add an artificial order by clause to to deal with different results.
Issues outstanding: - HDFS in ClusterExecutionIT needs to be thought out
