Extras Plugin

The Extras plugin will initialize the optional addon plugins from extras/ directory, if they were loaded.

Generally, for an extras plugin to have been loaded, 2 things must have happened:

1. The extras plugins must be present in extras/ directory, for example after running git submodule update
2. One or more extras plugins are added to the impress.js presentation (the HTML file) by the author using a regular <script> tag.

If one or more extras plugins were so added, this plugin will automatically discover them and perform initialization (such as calling mermaid.initialize()).

If no extras plugins are added to a presentation, this plugin does nothing.

Note that some extra plugins (like mathjax) initialize themselves immediately, and there's nothing to do here.
