/**
 * Content Blocks cbContentEditor Plugin
 * 
 * This plugin hides certain CB buttons from certain MODX user groups
 * and disables the drag and drop functionality, so that you can provide
 * some clients with a more locked down version of CB.
 * 
 * I would suggest setting up CB templates and defaults in the CB component manager,
 * so that predefined layouts are loaded automatically when a new resource is created.
