Wanted: Storage of HEP data via key/value storage solutions

Interface the ROOT I/O to key/value stores.

The processing of the data acquired by the LHC experiments proved to be extremely demanding during the data-taking period featuring a centre of mass energy of 7 TeV. The requirements in terms of computing resources will increase during LHC Season 2 following upgrades to the accelerator and the detectors. However, the funding for the computing infrastructure will not scale accordingly.
