Modified the conditions which check len(gate_desc) in order to support gate_desc with 'time' and or 'return_flag'
Added the extra time parameter in the (X_gate, Y_gate, Z_gate, had_from_rot, CNOT_from_CZ, CRX_from_CZ) functions during the 'builder < ' call, so that the these gates are created with the correct time tag. (circuit_builder.__lt__ was modified in the previous commit to allow for this.

As a result of finding a bug in #19 where some gates would disregard the
timeargument during theb.add_gate, I made some changes to the code:In
qsoverlay/gate_functions.py, the functionsX_gate,Y_gate,Z_gate,had_from_rot,CNOT_from_CZ,CRX_from_CZfailed to use the time parameter in a meaningful manner. I added the parameter to the tuple passed tocircuit_builder.__lt__.In
qsoverlay/circuit_builder.py, inBuilder.__lt__, I modified the conditions which verified thelen(gate_desc), in order to make them support the usage of thetimeAND/ORreturn_flag. It however assumes that, if both flags are used,timeshould precedereturn_flags.These changes should fix the bugs during the construction of
circuit_buildercircuits via theadd_gatemethod. It is still necessary to add time support to other places whereBuilder.__lt__is called. In the meantime, the changes I made shouldn't cause any conflict with those, however.Regards,
Diogo Valada
