First upload of the qtrl modules

Main module control.ctrlpulseoptim provides functions for optimising control
pulses for quantum systems. Relies on the other classes for processing.

Uses the BFGS (actually primarily the L-BFGS-B) algorthim, which is a quasi-second order Newton method for multivar function optimisation

Examples in the 'examples' folder to demonstrate usage.
1. Hadamard - a simple example of Hadamard gate synthesis
2. Lindbladian (open systems) - amplitude damping channel example
3. Symplectic - a coupled oscillator example
4. QFT - a 2 qubit example, showing alternative (more configurable) method for invoking the optimisation
How do people credit themselves (and their supervisors) in this case? I looked at cgranade's logging module for inspiration, but he has not included his own name in the file header. I assume  that the lines

should remain as they are. Could you point me in the direction of a good example pls?
