/*

 * Summary:      Core experiment function that applies any number of classes to all child elements

 *               contained in all occurences of a parent element (either with or without a specific class)

 * Parameters:   parentElementTag - parent tag name

 *               parentElementClass - class assigned to the parent; if null, all parentElementTag elements will be affected

 *               childElementTag -  tag name of the child elements to apply the styles to

 *               styleClasses - comma separated list of any number of style classes (using 2 classes gives the classic "zebra" effect)

 * Return:       none
