From Gerri:

- Add a new directory 'proof' under tutorials with a frame to run   PROOF tutorials and an example of non-data driven selector making
  some drawings.

  Run like this:

   $ cd tutorials; root -l
   root[0] .L proof/runProof.C+
   // Run locally with a number of workers equal to the cores in the machine
   root[1] runProof("simple")
   // H1 analysis reading the data via 'http'
   root[2] runProof("h1")

   To run on a cluster at 'master.domain' pass the master as second argument

   root[1] runProof("simple", "master.domain")
   root[2] runProof("h1", "master.domain")

- fix a missing include problem in h1analysis.C
