Optimize gate_to_node code

Added parameters for the pulse gate

…required positional arguments: 'time_func' and 'label'

fix 1: add back from_openqasm

1. Add runtime_job_id 2. Add back `from_openqasm` to ensure backward compatibility

fix: default runtime_job_id should be empty string

CircuitPlotManager has been implemented to support plotting the most commonly-used gates/instructions, with two simple examples uploaded. Please help to test whether it has no error integrating into dev-branch, for it was written firstly to work well with the odd version of pyquafu. Supports for other instructions, as well as more documentation and examples, will be added a little bit later. （线路绘图功能基本完成，稍加完善即可发布使用。请先测试与dev分支能够整合无误。使用说明文档和其余功能稍后添加。）

reload for dir-path mistake...

Some unused 'imports' were removed. And it's not suggested to use 'from xxx import *' to avoid namespace conflicts.

Add SXdgGate to quantum_element.py, sxdg() to quantum_circuit.py and also counterparts for Y. Matrices were written explicitly as array of numpy, symbols were also given.

1. Use self.add_gates() to check out position range.
2. Set default pos of barrier() to be None which means to act on all qubits.
3. Integrate plot_circuit() from visualisation module.
(Have tested by plotting.)

Outer access to element_gates remains the same for all gates have been imported in __init__.py

1. Now allows updating by several commands of .measure(pos, cbits) on different positions.
2. Also allows to measure all qubits directly by measure()
3. Add uniqueness check.

And set a class attribute 'name' for the subclasses.

Set 'name' as an abstract property for any abstract base class like Instruction and as a class attribute for concrete class like XGate. Some logic for adding `matrix` to QuantumCircuit and its subclasses. Matrices of gate-cls with paras are properties decorated by @Property, which update matrices automatically when parameters updated.

Please help to test.

…self.unitary()

With unitary decomposer test.

From now on you may look up all the available concrete gate class by:

for name, cls in QuantumGate.gate_classes.items():
    print(name, cls.__name__)

Similar mechanism is to be implemented for Instruction.

Customized labeling of bits allowed, see new example adder.py for details.

1. Use 'if xxx is not None' instead of 'if xxx'.
2. Fix overlapping of parameter text on plot.

1. Use 'if xxx is not None' instead of 'if xxx'.
2. Fix overlapping of parameter text on plot.

Hopefully, plot_circuit now supports all the basic gates.

Please add circuit examples into module 'benchmark'.
