Rename get_power.pl to dbt3-power-score
Add index to pgsql refresh stream 2
Plot mean of throughput tests

Stop plotting each throughput stream separately.  It will be unreadable
as more throughput streams are used to test.  Also made initial pass as
drawing geometric and arithmetic means.
Super simple scripts

Don't run the scripts in place anymore.  Rely on setting environment
variables to set parameters for dbgen and the postgres scripts.  The
other DBMS systems' scripts will also need to be updated.  This will
hopefully make it easier to work with multiple databases without having
to rebuild all the scripts in order to switch.
Remove logic to run repeated performance tests

I think this simplifies the scripts.  Multiple performance tests can
still be run by running the dbt3-run-workload script without a load
tests.  This also simplifies the post processing scripts which didn't
really handle processing multiple performance tests anyway.
Remove perl modules no longer in use
Removed unused gen_data.sh script
Rename scripts with dbt3 scheme
Remove dbdriver dir redux

This was supposed to have been removed previously.
Update report script

Use the data collected during the test instead of checking the system
that the script runs from.  The report generator may not be run on the
same system as the test was, so certain system details were of the
system running the report as opposed to the system under test.
