Quanlse 2.2.0

In this version we have added the following new features：

• Add Superconduct.Lab package for rapidly designing superconducting experiments, including the scan or normal experiments; it also provides the interface Superconduct.Lab.LabSpace to access the data service, Superconduct.Lab.Runner to connect the experiment devices or simulator.
• Add Utils.ControlGate module to define the composition of the logic gate and the corresponding control pulses.
• Add Utils.WaveFunction module to define the preset waveform functions.
• Add Simulator.SimulatorAgent module to define the agent served for Quanlse Simulator, it provides quick access to all data and functions of Quanlse Simulator; it is based on the Superconduct.Lab package.
• Add Utils.Functions.subspaceVec() function to extract a population vector in a subspace.
• Add symbol QOperator shortcuts QOperator.chXY(), QOperator.chX(), QOperator.chY(), QOperator.chZ(), QOperator.chRO() which has no matrix definition in QOperator module.
• Add TrappedIon.Optimizer.OptimizerIon module to calculate robust laser sequence
• Add TrappedIon.Optimizer.QIonEvolution module to define basic evolution function of trapped ion system
• Add TrappedIon.QIonSystem module to define basic class of robust control laser and trapped ion Chip property.
• Add TrappedIon.QIonTrajectory module to define the phonon trajectory evolution and visualize the ion-ion coupling.
  We have improved the following existed function:
• Improve module QWaveform, add dump2Dict(), dump2Json() and parseJson() methods to fully support JSON serialization and deserialization; QWaveform.addWave() method now is also supported to pass string-formatted waveform function name to argument f to call the preset waveforms.
• Newly add the Superconduct package, and move the Calibration/Simulator packages into Superconduct.
