/**
 * Returns the MonsterInsights combined object that you can use for both
 * MonsterInsights Lite and Pro Users. When both plugins active, defers to the
 * more complete Pro object.
 *
 * Warning: Do not use this in Lite or Pro specific code (use the individual objects instead).
 * Also do not use in the MonsterInsights Lite/Pro upgrade and install routines.
 *
 * Use this function like you would a global variable, except without needing
 * to declare the global.
 *
 * Prevents the need to do conditional global object logic when you have code that you want to work with
 * both Pro and Lite.
 *
 * Example: <?php $monsterinsights = MonsterInsights(); ?>
 *
 * @return MonsterInsights The singleton MonsterInsights instance.
 * @uses MonsterInsights::get_instance() Retrieve MonsterInsights Pro instance.
 * @uses MonsterInsights_Lite::get_instance() Retrieve MonsterInsights Lite instance.
