/**
* Loader class, a Singleton. Coordinates potentially multiple installations of
* the Font Awesome plugin code, and ensures that the latest available semantic
* version is selected for execution at runtime. Exposes a few public API
* methods for initialization (activation), deactivation, and uninstallation
* of plugin code.
*
* Font Awesome plugin installations may be installed either directly
* as a plugin appearing in the plugins table, or as a composer dependency
* of any number of themes or other plugins.
*
* We only have in mind various installations of this code base,
* of course. Not other non-official Font Awesome plugins. We don't try
* to anticipate what _other_ potentially conflicting plugins might be installed.
*
* All Font Awesome plugin installations should attempt to load themselves via this loader,
* which will ensure that the code for plugin installation with the latest
* semantic version is what actually runs. It also ensures appropriate
* handling of initialization, deactivation and uninstallation, so that the
* actions of one plugin installation don't interfere with another's.
*
* Refer to `integrations/plugins/plugin-sigma`
* in this repo for an example of how to load the Font Awesome plugin code
* via this Loader when including it as a composer dependency.
*
* The client code should `require_once` the `index.php` found
* in the root of this code base:
*
* ```php
* require_once __DIR__ . '/vendor/fortawesome/wordpress-fontawesome/index.php';
* ```
*
* For example, suppose the following scenario: A later version of the plugin
* is installed from the WordPress plugins directory and appears in the
* plugins table. It is activated.
* Then suppose a page builder plugin is installed and activated. That page builder
* plugin includes this plugin code as a composer dependency. In that case,
* the plugin code with the later semantic version will be the one loaded
* and executed at runtime.
* The page builder plugin should work just as expected, even though it would
* be running against a newer version of the Font Awesome plugin code than it
* had shipped in its own vendor bundle.
*
* Now suppose that the site owner deactivates and deletes the plugin that
* appears in the plugins table, the one that had been installed from the
* WordPress plugins directory. Because this loader knows that the page builder
* plugin's installation is still present, that deactivation and uninstallation
* will not cause the Font Awesome plugin's options and transients to be removed from the
* database. And as soon as that plugin installation is removed,
* the Font Awesome plugin installation included in the page builder plugin's
* composer vendor bundle is automatically promoted and runs as expected with
* no change to the plugin's state in the database.
*
* This loader pattern follows that of [wponion](https://github.com/wponion/wponion/blob/master/wponion.php).
* Thanks to Varun Sridharan.
