Merge branch 'master' of github.com:lip6/coriolis

* Change: In cumulus.block.configuration and cumulus.block.htree, two new
    configuration parameters allow to specify the offset of the horizontal
    branch of the H-Tree manually:
        cfg.spares.htreeRootOffset (first level of the tree)
        cfg.spares.htreeOffset     (subsequent levels)
      The offset is given in number of tracks.
