CC-light basic eQASM compilation

[AdriaanRol]

The basic compilation should include

• single qubit gates
• two qubit gates
• measurement

This issue can be closed when:
There is a working python test containing a basic program that gets compiled and produces valid CC-light instructions.

• A basic program must contain single qubit gates, two qubit gates and measurement.
• The basic program should contain an example configuration file.
• The validity of the output must be tested using the CC-light assembler from within the test.
• If possible the validity of the output must be verified by hand by testing on hardware and/or using the simulator. If this is valid, the output eQASM should be saved in the golden folder for future tests.

Current expected delivery date: Aug 25.

@Nader-Khammassi @imranashraf I think we can close this.
There are still some open issues (known bugs etc) but I would say that the basic functionality is there.

Yes, this has been mostly taken care of in https://github.com/DiCarloLab-Delft/OpenQL/issues/37
