		/**
		 * Explanation of MonsterInsights core options
		 *
		 * By now your head is probably spinning trying to figure
		 * out what all of these version options are for. Note, I've abbreviated
		 * "monsterinsights" to "mi" in the options names to make this table easier
		 * to read.
		 *
		 * Here's a basic rundown:
		 *
		 * mi_current_version:  This starts with the actual version MI was
		 *                        installed on. We use this version to
		 *                        determine whether or not a site needs
		 *                        to run one of the behind the scenes
		 *                        MI upgrade routines. This version is updated
		 *                        every time a minor or major background upgrade
		 *                        routine is run. Generally lags behind the
		 *                        MONSTERINSIGHTS_VERSION constant by at most a couple minor
		 *                        versions. Never lags behind by 1 major version
		 *                        or more generally.
		 *
		 * mi_db_version:        This is different from mi_current_version.
		 *                        Unlike the former, this is used to determine
		 *                        if a site needs to run a *user* initiated
		 *                        upgrade routine (incremented in MI_Upgrade class). This
		 *                        value is only update when a user initiated
		 *                        upgrade routine is done. Because we do very
		 *                        few user initiated upgrades compared to
		 *                        automatic ones, this version can lag behind by
		 *                        2 or even 3 major versions. Generally contains
		 *                        the current major version.
		 *
		 * mi_settings:            Returned by monsterinsights_get_option_name(), this
		 *                        is actually "monsterinsights_settings" for both pro
		 *                        and lite version. However we use a helper function to
		 *                        retrieve the option name in case we ever decide down the
		 *                        road to maintain seperate options for the Lite and Pro versions.
		 *                        If you need to access MI's settings directly, (as opposed to our
		 *                        monsterinsights_get_option helper which uses the option name helper
		 *                        automatically), you should use this function to get the
		 *                        name of the option to retrieve.
		 *
		 * Therefore you should never increment mi_db_version in this file and always increment mi_current_version.
