   In TProofBench::DrawCPU, add possibility to extract of a couple of numbers supposed
   to give an idea of the computing specs of the cluster being benchmarked. These are
   the maximum rate for the standard CPU intensive task and the normalized, per worker,
   rate. Both are expressed in RNGPS (RaNdom Generation Per Second).

   A new static method TProofBench::GetPerfSpecs provides a simpler interface to this
   new options, optionally scanning a directory for proofbench outputs and giving the
   possibility to choose which file to use to extarct the numbers:

   The patch also adds a TNamed in the proofbench output file with a string describing
   the setup used for the test (in the example above: 'PROOF at kiaf.sdfarm.kr, 96 workers').
   The name of the TNamed is 'PB_description'.

   A web page is being created with the specs from some clusters where the bench has been run.

   In proofbench:
   - Add setter for the number of files per worker to be created during dataset generation
   - In TSelEventGen:
     - fix bug in testing write permissions on the altrenative basedir
     - add check on the free space on the device and skip file generation if less than 10%
       or less than 1 GB.

   Few fixes in 'proofbench':
   - Make sure it can be run from any directory and no matter how ROOT was installed;
     the paths to the PAR files were such that it could be run only from a own build
     and from $ROOTSYS. The default PAr files are now exported to $ROOTSYS/etc/proof/proofbench
     and in <etcdir>/proof/proofbench for a prefix installation.
   - Fix the name of the setter/getter for the file generator parameters and selectors
   - TSelEventGen, add the possibility to change only the generating function, passed
     as TMacro.

  From S. Ryu:
  - In TProofNode::ActivateWorkers use the new functionality of TProof::(De)ActivateWorker.
  - Fill the default dataset BenchDataSet with file meta data so that it can be registered
    with "T" (trust information) option;
  - Add regenerate option to TProofBench::MakeDataSet
  - Add fDebug member in TProofBench to control to switch on/off saving of detailed information
    about the queries in the test.

  From S. Ryu (KISTI) and me:
  - Add some missing protections
  - Make sure that the Url to access remotely the generated files is the one set by the
    administrator via the env  LOCALDATASERVER.
  - Add the possibility to use a different PROOF instance to clear the cache

  From Sangsu Ryu (KISTI) and me:
  First part of the patch for the new PROOF bench suite, a framework to run CPU and IO benchmarks
  with default selectors/data or with user-provided ones.
  The code is located under proof/proofbench. The module is not yet activated in Makefile
  (it will be soon).
  See http://root.cern.ch/drupal/content/new-benchmark-framework-tproofbench for the documentation
  under preparation.
