Just because most of the "problem solving" is done by the measurement process. As the code for measuring gets more complicated, we can move it to another file. |

Depends on #3683
This will be an internal function used by the next-generation Python device. The logic is extracted from the device to allow easy simulation of batches and the ability to distribute multiple simulations across different threads.
This first iteration will only support state-based measurement of observables with diagonalizing gates. Later PR's will add state-based measurements of observables with sparse or dense matrices and sample-based measurements.
This function will allow simultaneous measurement of non-commuting observables.
