Detailed Description

References one or more qubits of a Qureg.

This enables access to only a part of a Qureg, addressed by one or more qubits. The entries of a QuSubReg (accessed by []) are in binary order, addressed by the qubits in the QubitList given to Qureg::getSubRegs(qubits), with the first qubit added to the list being the least significant (rightmost, fastest varying...). Note that a QuSubReg contains references, thus manipulating an amplitude by means of QuSubReg[] will directly influence the underlying Qureg. Which is of course what one usually wants.
