/**
 * Is This ExactMetrics Pro?
 *
 * We use this function exactmetrics_to determine if the install is a pro version or a lite version install of ExactMetrics.
 * If the install is a lite version we disable the install from admin functionality[1] for addons as WordPress.org requires us to,
 * we change the links for where to get support (wp.org forum for free; our site for pro), we use this determine what class to load as
 * the base class in addons (to avoid fatal errors) and we use this on the system info page to know what constants to display values for
 * as the lite and pro versions of our plugin have different constants (and names for those constants) you can declare and use.
 *
 * [1] Note: This is not "feature-locking" under GPL guidelines but rather something WordPress.org requires us to do to stay
 * in compliance with their rules. We wish we didn't have to do this, as in our oppinion this diminishes the user experience
 * of users installing our free and premium addons, and we'd love to turn this on for non-Pro installs, but we're not allowed to.
 * If WordPress.org ever changes their mind on this subject, we'd totally turn on that feature for Lite installs in a heartbeat.
 *
 * @todo  Are we allowed to turn on admin installing if the user has to manually declare a PHP constant (and thus would not be on
 * either by default or via any sort of user interface)? If so, we could add a constant for forcing Pro version so that users can see
 * for themselves that we're not feature locking anything inside the plugin + it would make it easier for our team to test stuff (both via
 * Travis-CI but also when installing addons to test with the Lite version). Also this would allow for a better user experience for users
 * who want that feature.
