 * I uninstalled the plugin and deleted it. But the meta data and the associated
   fields created by the plugin in the database still exists. How do I purge all
   data?

 * I am little by little improving our uninstall process. This is one of those things
   that I know really matters but we’re a small team (I do 100% of the dev) and 
   my users don’t care about uninstall scripts, only those who don’t like LifterLMS
   and, yes, you’re important too and I don’t intend to screw your database up but
   I am also almost always at absolute capacity simply trying to keep up with support.
   Please understand and accept my apologies for this inconvenience.
 * If you add the following to your wp-config.php file and then deactivate LifterLMS—
   most options and some content created by LifterLMS will be deleted upon plugin
   deactivation:
 * `define( 'LLMS_REMOVE_ALL_DATA', true );`
 * After deactivating you can then remove that from your config file.
 * As far as deleting other content:
 * 1) Delete custom posts from your wp_posts table: course, lesson, llms_quiz, llms_question,
   llms_membership, llms_access_plan
 * 2) Delete custom tables — anything that starts with “wp_lifterlms_” can be safely
   deleted
 * 3) Theres is a ton of postmeta data that will be left behind. I wish there was
   a foolproof way to do this (part of the reason why I don’t have a great uninstall
   script yet is it is a bit difficult to idenfity)…
 * Anything with the meta_key starting with `_llms` can be deleted. Though, a quick
   SQL delete can purge those.
 * As always, back up before deleting stuff (just in case).
 * Hope that helps and, again, I’m sorry!
