/**
* Subtitles uninstall functions.
*
* This file is triggered when Subtitles is uninstalled. It's mostly here for demonstration
* purposes and also in case there is a future need for it.
*
* Let's think a little bit about the way that Subtitles uses data. Users enter subtitles
* into their posts, pages, and subtitles-supported custom post types. These subtitles
* are what I would consider non-trivial post meta. They contain content that's relevant
* to users' posts, so I do not think that automatically deleting them is a wise move.
*
* Plugin deletion also isn't a fair predictor that the user wants to remove all of his subtitles.
* What if he's uninstalling the plugin in order to upload a fresh copy? What if an initial install
* didn't go as well as planned and the user wants to wipe out Subtitles before uploading a fresh copy?
* I'm worried that if someone uninstalls the plugin and then installs it again only to find all of their
* post titles gone, they will be very unhappy.
*
* In the future I could see there being a need for people to be able to delete all of their subtitles
* in one fell swoop, but right now I do not think that this is necessary.
*
* @since 1.0.0
* @package Subtitles
