[Docs][Feature] Add the ability to search through the documentation

[mathieucaroff]

The documentation is still a bit messy and it's hard to find where concepts are documented. For instance, I was trying to find information about slide fragments, but nothing showed up in the API Reference.

Description

Add the ability to search through the documentation.

Proposal

This could be done via a search bar at the top of the page. This could rely on Algolia, since Spectacle is an opensource project.

Links / References

• Algolia:
  • https://www.algolia.com/pricing/ -> It's free while the userbase is small
  • https://www.algolia.com/for-open-source/ -> It should be free as long as Spectacle is Open-Source

After-the-fact-note: There is not a single hit for "Fragment" when searching methodically through all the pages of the documentation. Looking into the code, I saw that there's no code in Spectacle for fragments: Fragments actually are a recipe. Still, this recipe should be documented, as the concept is presented in the demo, see here.
