Calculates minimal and maximal depth of circuit and depth for all circuit wires.

Function calculates minimal and maximal depth of circuit. A depth is length between circuit input to circuit output. Function additionally returns minimal and maximal depth for all circuit wires (inputs and gate outputs). It returns tuple with elements:

• list of minimal and maximal depths for all circuit wires. Entry index is circuit wire index, entry value is pair of minimal and maximal depth.
• minimal depth of circuit.
• maximal depth of circuit.
