 * This function basically adds the parent page to the sublevel but only if the sublevel is empty!
 * It is also used to demonstrate the menu state items
 *
 * Example can be found in the testsite package at the page-path "/Intro/TypoScript examples/Menu object examples/Fake menu items/" and "/Intro/TypoScript examples/Menu object examples/Menu state test/"
 * This TypoScript configuration will also demonstrate it ("fake menu items"):
 *
 * includeLibs.fakemenuitems = media/scripts/example_itemArrayProcFunc.php
 * page = PAGE
 * page.10 = HMENU
 * page.10.1 = TMENU
 * page.10.1.expAll = 1
 * page.10.1.NO {
 *   allWrap = | <br />
 *   linkWrap = <b>|</b>
 * }
 * page.10.2 = TMENU
 * page.10.2.itemArrayProcFunc = user_itemArrayProcFuncTest
 * page.10.2.NO {
 *   allWrap = | <br />
 *   linkWrap = <b> - |</b>
 * }
 *
 * @param	array		The $menuArr array which simply is a num-array of page records which goes into the menu.
 * @param	array		TypoScript configuration for the function. Notice that the property "parentObj" is a reference to the parent (calling) object (the tslib_Xmenu class instantiated)
 * @return	array		The modified $menuArr array
