----------------------------------

    Attachment: hive-713.2.donot.patch

More changes, but not yet ready to patch. Remaining tasks:

- in each operator, if there are new counters, call addToCounterNames() in initialize
- from SemanticAnalyzer, after plan generation walk all tasks and call assignCounterNameToEnum
for each operator
- in each Operator.process increment counters

- in driver add call to return plan, dump queryplan to history file
- in ExecDriver.progress walk all operators and call updateCounters and dump out stats to
history file
- in queryplan walk tasks/operators and return plan which includes counters
- in separate class provide command line option to parse history file and print latest plan
