/* Personalize Snippet for Revolution */

/* ::::::::::::::::::::::::::::::::::::::::
 * Snippet Name: Personalize
 * Short Desc: returns a chunk if the user is logged in, otherwise calls another
 *::::::::::::::::::::::::::::::::::::::::
 * Description:
 * Checks to see if users are logged in and displays yesChunk if the user
 * is logged or noChunk if user is not logged. Insert only the chunk name as
 * param, without any tags. Can use a placeholder to output the username.
 *
 * TESTED: can be used more than once per page.
 * TESTED: chunks can contain snippets.
 *
 * Example Usage:
 *
 *    [[!Personalize?
 *        &yesChunk=`HelloUser`
 *         &noChunk=`Register`
 *         &ph=`name`
 *     ]]
 *
 * Create Chunks named HelloUser and Register, the first will be
 * shown to a user logged on in the current context,
 * the second to other users.
 *
 * ADDED in 3.3.1 by Vasia123:
 *    
 *    1. &noChunk=`@CODE:<b>Please login!</b>` - inline snippets
 *    2. &ifIds=`1,3` - additional check for users ids. yesChunk will
 *         only be shown to logged-in users in the list.
 *    
 * ADDED in 3.6.0 by Vasia123:
 *    
 *    1. &allowedGroups=`Editor,Administrator` - check if user is
 *       in any allowed group
 *    
 *    
 * Placeholder [[+name]] will show the user's name in the yesChunk or
 * elsewhere on the page.
