function changeLocType(strLocType){
// Function name      – changeLocType
// Description        – This function changes the values of the
//                      inputs in the form when the user clicks
//                      on one of the LocType radio buttons. The
//                      values of the inputs of the LocType chosen
//                      are set to the values of the location
//                      components from the cookie. The values in
//                      the other components are cleared out.
// Usage              – onclick="changeLocType(strLocType)"
// Parameters passed  – strLocType - the value of the radio
//                      button clicked.
// Return value       – None
// Function called by – Click action on intersection radio buttons in frmNoMatch
//                      form.
// Functions called   – None
// Global variables   – strXX where XX is one of the address components.
