Pr/1.4.6

[mpvanderschelling]

Major changes

• Added documentation on SLURM job scheduler. Added sphinx-tabs as dependency when building documentation.
• WIP: New back-end of _Data that relies on lists instead of pd.DataFrame. This has not yet replaced the pandas back-end but tests are passing with the new _newdata.py module.
• Removed unused method Domain.from_yaml.
• Removed unused _Data.fill_output method
• Output of benchmark functions is now a float instead of np.ndarray[float]. Necessary to pass tests for new back-end, won't affect pandas back-end.

Minor changes

• Refactoring parts of the ExperimentSample code to be more robust to changes in the back-end
• Moving factory methods to appropriate modules
• Removed try_import; import checks are moved to extension packages
• Added __version__.py file
• Updated docstrings to remove leading spaces

Bugfixes

• Correct equality operator of Domain to also compare for output_space attribute
• Closes Selecting experiments from ExperimentData copies columns incorrectly #241
• Closes ExperimentData hyperlink in the docs are not working #191
• Closes Optimization requires your domain to have names x0, x1, x2, etc. #240
• Closes Adding documentation about using f3dasm and slurm resource schedulers #243

[BernardoFerreira]

Good job initializing the refactoring process of the back-end and improving the documentation to leverage f3dasm on HPC. A few bugs were also fixed, namely those unexistent hyperlinks to quickly jump to the Classes docs - nice!

Good to go!
