:pencil: (time_log() decorator in timing.py): Updated docstring.

Deleted old timing_example.py and renamed tester.py->timing_example.py

Added UTC time logging.

timing.time_log() can now handle non-JSON-serializable objects in a safe manner.

Added function is_jsonable() to timing.py

Modified timing.py to use jsonpickle https://jsonpickle.github.io/#module-jsonpickle, because some of the possible arguments are very likely to not be JSON-serializable. Added tester.py

Modified timing.py, adding a new decorator that logs timings to a json-lines file. Added an example timing_example.py

Added comments and accents.

Added a coment : Do not use easyimport anymore.

Testing inegration with google colab.

Comented out: 'import timing' on multiresunet.py and added easyimport.py

Next commits will include more docstrings.

Functional MultiResUNet()

Implementation error : wrong order of parameters when calling functions inside MultiResUNet()

Added MultiResUNet() function.
