Adding options to build out symbolic links to partitioned data for specific benchmark tests. Also have a method to copy queries over and change the collection references to the symbolic links.
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.
Clean up items for the weather scripts.
Updated the generated station xml to mirror web service.
Added a reset option to partitions and queries.

The new option allows for all existing data to be removed before running the file copies. Makes a clean start to the data.
Enabling hash based join.

The changes involve two new rules that allow switching between Algebricks Builtin Identifiers and VXQuery equivalent expressions. One more rewrite rule was included to move expressions out of the inner join to allow for hash join to be enabled on variables. Other changes connect these rules to allow for complete hash join implementation.
Query update to work with generated data on smaller data sizes.
Improve search for functions based on things I learned from join.
Removed change to comparator factory provider.

The change removed all the result for the join operation.
Removed extra space.
Added some support queries to help understand the join condition.
Added logging to the benchmark script and a new join query.
