 *
 *  CondFormats/PPSObjects/plugins/CTPPSBeamParametersESSource.cc
 *
 *  Description :  - Loads CTPPSBeamParameters from the CTPPSBeamParametersESSource_cfi.py
 *                   config file.
 *                 - Currently, one single set of beam parameters is provided. Just to be
 *                   ready in time for 10_4_0 and allow simple tests.
 *                 - To be further developed to provide multiple sets of parameters
 *                 - Needed while CTPPSBeamParameters is not available in database
 *
