Class Description

 Base class for BRAHMS databases. Individual database classes can
 inherit from this and then define the mathods in needs. E.g., a
 calibration databse classs, can define the methods
 "BrCalibObj* GetAround(time_t t)" to get calibration valid around
 the unix_timestamp t, and a run database could define "BrRunInfo*
 GetRun(int no)" etc.

 The actual database name is stored on the TNamed::fTitle, while the
 symbolic name is stored in TNamed::fName
