Add scripts to produce documentation using jsdoc

[tahini]

fixes #591

Add yarn scripts to generate documentation for the evolution-common javascript code.

TODO

• Document the typescript code instead, so that the types are also documented
• Document all the evolution packages, not just common
• Provide a higher level "glue" to document high level concepts that can then link to the jsdoc complete documentation of the packages.

To use this commit, you need to install jsdoc globally on your system with

npm i -g jsdoc

I spent a good 15 minutes on this, no more, there's a lot of improvements to do, but it's promising.

The idea comes from a comment by @greenscientist on #583 to have a high-level idea of what's going on. And since I did try to document the code as much as possible, for extension mechanisms at least, it would be great that this doc can be made available somehow at a high level for others to see without reading the code.

Let me know if you think it,s worth spending a few more hours on this to make it "perfect"

Yes, this is really interesting, I could see myself looking at this when trying to find or understand a helper function for Evolution. This has so much potential to help us document our projects.

[greenscientist]

Yes, that's nice. We'll need to find a way to publish it some where and link it into our static doc.

@tahini @samuel-duhaime should we rabase and merge?

[samuel-duhaime]

Yes, this could be nice. Let's rebase and push this @tahini .

See the TODO, it is more than a simple rebase and merge, but if we want it, I'll update this.
