// Class:      WriteCTPPSBeamParameters
//
// Description: Test analyzer for CTPPS beam parameters condition data
//
//              Simple analyzer that writes one CTTPSBeamParameters record into a sql
//              database file, as a test of offline conditions implementation.
//              Another analyzer is then used to retrieve these conditions.
