 * Remove Gravity View assets from everywhere other than on single View pages.
 *
 * If script or style source starts with `{MyURL}/wp-content/plugins/gravityview` and we're not on a single View, dequeue it.
 * If you create a custom GravityView plugin of your own and don't want it affected by this snippet, start your plugin
 * folder name with anything other than 'gravityview'.
