Memote

------------------
* Allow users to selective recompute the history of results.
* Skip commits in the history that did not change the model file.
* Change format_type on experimental tests from `count` to `percent`
* Fix typo in `test_basic.py` that lead to tests returning `null` which breaks
the diff report frontend.
* Update the diff report to properly show errored and skipped tests
* Fix issues with asynchronicity on the diff report.
* Change format_type on experimental tests from ``count`` to ``percent``
* Fix typo in ``test_basic.py`` that lead to tests returning `null` which
breaks the diff report frontend.
* Update the diff report to properly show errored and skipped tests

------------------
* Finalize testing comparing with experimental data (growth and esentiality).
* Temporarily disable ``test_find_inconsistent_min_stoichiometry``.
* Update the nullspace function.
* Improve optlang compatibility.
* Add test ``find_medium_metabolites`` to detect and display all substrates
capable of being taken up by model
* Display the score on History and Snapshot reports.
* Invert the colour coding.
* Display results as percentages.
* Add ability to generate a diff report which compares two or more models.
* Annotation of metabolite shortlist simplified.

------------------
* Refactor internal API and JSON object creation.

------------------
* Expose more of the internal API to the top level.
* Also, remember to carry a towel!

------------------
* Add test ``find_duplicate_reactions`` to detect duplicate reactions in model
* Add dynamic upper and lower bounds. They are based on the most extreme bound
values given in a model (if none exist -1000 and 1000 are chosen as defaults)
* Fix logic in ``find_bounds`` function in ``helpers.py``

------------------
* Make the report type variable a string in the ``index.html``.
