//
// This class represents the value(s) of
// a DCS data point at a given timestamp.
// It stores different data types, the current implementation has a member for all of them.
// This is definitly not efficient, but the only way to use the automatic streamers generated by ROOT.
//
// Each element of this value series has two fields:
// fValue - primitive value which represents the real measured value
// fTimestamp - timestamp when the measurement was made
//
