pauli_product_phase

 pauli_product_phase (x1:bool, z1:bool, x2:bool, z2:bool)

Determines the power of i in the product of two Paulis.

For example, X*Y = iZ and so this method would return +1 for X and Y.

The input Paulis are encoded into the following form:

x z | Pauli
----+-------
0 0 | I
1 0 | X
1 1 | Y
0 1 | Z
