** fillDependentSelectBox(selectBox, selectedVal)
** ===============================================
** Fill a dependent select box with desired options. E.g., in a 
** two-level select-box construct (see navigate.html), the master
** select box would use onChange to call fillDependentSelectBox(),
** and the dependent select box would use onChange to call openURL().
**   selectBox - dependent select-box object to fill
**   selectedVal - currently selected select-box value
**
** Note: This fillDependentSelectBox() code is tailored specifically 
** to the select-box constructs on the navigate.html demo page. You'll
** have to modify the code to fit your select-box construct needs. The
** logic will be the same, but the details will be different.
