 /**
  * Creates and returns reference to a user defined object.
  * This function can return an object reference if you like. Just prefix the function call with "&": "$objRef = &t3lib_div::getUserObj('EXT:myext/class.tx_myext_myclass.php:&tx_myext_myclass');". This will work ONLY if you prefix the class name with "&" as well. See description of function arguments.
  * Usage: 5
  *
  * @param	string		Class reference, '[file-reference":"]["&"]class-name'. You can prefix the class name with "[file-reference]:" and t3lib_div::getFileAbsFileName() will then be used to resolve the filename and subsequently include it by "require_once()" which means you don't have to worry about including the class file either! Example: "EXT:realurl/class.tx_realurl.php:&tx_realurl". Finally; for the class name you can prefix it with "&" and you will reuse the previous instance of the object identified by the full reference string (meaning; if you ask for the same $classRef later in another place in the code you will get a reference to the first created one!).
  * @param	string		Required prefix of class name. By default "tx_" is allowed.
  * @param	boolean		If set, no debug() error message is shown if class/function is not present.
  * @return	object		The instance of the class asked for. Instance is created with t3lib_div::makeInstance
