// <synopsis>
// The old way of getting a type number for a Quantum<T> uses the Register
// class. This did not work well with shared libraries, because each shared
// library gets its own static type data. Hence a type generated in one
// python module sometimes mismatched the type for the same Quantum in
// another module. For instance, it appeared that whem first loading
// pyrap.tables and thereafter pyrap.quanta, things went wrong.
//
// Therefore this class has been developed that returns the type for the
// Quantum template types used by QuantumHolder.
