A few clean up items when cleaning up and standardizing the benchmark config file to look similar the server config file.
Preparing for local speed up tests.

I removed the queries that are currently not working. Also fixed a bug referencing files directly in the query instead of through the data links. Removed some debug code.
Added a check to make sure the data file was created.
More tweaks to make the benchmark cluster queries.

* Updated the data links to real partitions.
* Updated the query copy process.
* Simplified the example config file.
Added new InlineNestedVariablesRule.

The rule modifies the Algebricks rule for InlineVariablesRule to include nested plans in the processing.
Added license and option to run a single query.
Fixed Max and Min when local aggregate does not return a result.

The min or max function now always returns a result. If no result is available, empty sequence is returned. The aggregate step function also now considers an empty sequence as valid input.
A few more tweaks to the weather scripts.

* now supports all queries.
* example has been update to a single partition.
Added support for unnest in expression toolbox sequence matching.
