`-print-csp-source`: print CSP output

`-print-final-submission`: print final IR submission (NISQ) or apply (FTQC)

`-print-opt-stats`: print runtime pass execution info

# Demo1: 

- No opt: print-final-submission to show final XACC IR tree for backend submission

```

qcor simple_circuit.cpp -print-final-submission

```

- Opt: level 1

```

qcor -opt 1 simple_circuit.cpp -print-final-submission

```

- With opt stats:

```

qcor -opt 1 simple_circuit.cpp -print-final-submission -print-opt-stats

```

- Trotter example:

```

qcor trotter_decompose.cpp -print-final-submission 

```

```

./a.out -dt 0.05 -steps 10

```

```

qcor -opt 1 trotter_decompose.cpp -print-final-submission 

```

```

qcor -opt 2 trotter_decompose.cpp -print-final-submission 

```

# Demo2: 

- Simulator

```

qcor -qpu qpp ghz.cpp 

```

- IBMQ

```

qcor -qpu ibm:ibm_lagos ghz.cpp

```

```

qcor -qpu aer:ibm_lagos ghz.cpp

```

- IonQ: 

```

qcor -qpu ionq ghz.cpp

```

```

qcor -qpu ionq:qpu ghz.cpp

```

- Atos QLM:

```

qcor -qpu atos-qlm ghz.cpp

```

(25-q max)

# Demo3:
