Iterative Quantum Phase Estimation bug

[debaarjun13]

I believe in the new module for the Iterative Quantum Phase Estimation there is a problem where there is a reordering of the qubits of the unitary operator when the circuit is being formed. The module runs fine for a 2 qubit circuit but creates problems when more than 2 qubits are involved .
Is it mainly due to the transpilation done during run time?
I tackled the issue by coding the unitary operator in a reversed manner and then flipping the ordering of the qubits in the source code (it is funny how the reverse ordering does not cause any problems during circuit composing)
