MODE-1323 added Google box chart report for aggregate results

-created a new module used for aggregating the results produced by the other modules
 -implemented a Google charts based report which displays all the repositories side-by-side
MODE-1323 added a Boxplot report for each of the tests
MODE-1323 fixed some warnings and some style issues
MODE-1323 added D3 charts for the aggregated reports

-renamed some API classes so they have shorter name
-renamed module 2.x to 2.7
-renamed module 3.x to 3.0
Corrected compilation errors/warnings

Several compilation errors/warnings were due to incomplete JavaDoc and incorrect visibilities.
All were minor changes
Updated/improved performance suite
MODE-1620 Import/clone performance test
MODE-1620 Rename test workspace to allow execute jackrabbit tests
Updated the ModeShape transitive dependencies, some of which are no longer available in the Maven repositories. Also changed 3.0.0.Beta1 to 3.0.0.Beta4
MODE-1648 Used the newly-created ModeShape BOMs
Changed the performance test suite to support mulitple configurations

The suite was previously only testing in-memory configurations (e.g., no persistence), which isn't really
a realistic scenario. (It is still useful and interesting as a test.) So I changed the framework to allow
multiple configurations, where each configuration is set via a Maven profile. Currently there are two
configurations: "local-inmemory" and "local-filesystem".
Additional shell script to more easily run the suite for all configuration.
Minor changes and fixes for compiler warnings
Merge pull request #10 from rhauch/perf-test-multi-config

Minor changes and fixes for compiler warnings
Updated several areas around reports:
- they are now generated under the same root as the other modules, using a hierarchical structure based on the execution timestamp
- they include information about the hardware on which the tests were run (via the Sigar information)
- various other small code changes
Made the performance test suite fault tolerant to tearDown()
Added 3.0.1.Final
Added 3.0.1.Final
Added more versions and tried to fix error
Changed the way report & test data output is configured and updated several configuration options for various ModeShape versions to workaround existing bugs: see MODE-2049 and MODE-2050.
