/* Unfortunately this function has proven extremely difficult to implement due to the input validation needed.
Validation rules are broken down into a :
1) Check to see if either an initial route, or a route has been reset by setting last successful route values to null.
2) Check to see we have initially defined only a (from) route point, AND there is a difference to a previous (to) route point.
3) Check to see we have initially defined only a (to) route point, AND there is a difference to a previous (from) route point.

4) Check to see if we have initially defined only a (from) route point.
5) Check to see if we have initially defined only a (to) route point.
6) Check to see if a route has changed because of different current and previous keys.
7) Check to see if there is a difference to previous (from & to) route points.
8) Check to see if there is a difference to a previous (from) route point.
9) Check to see if there is a difference to a previous (to) route point.
    Note: 20090223 George Petrakis - Have commented out steps 3 & 4 as they were never executed during console debugging. 
    No problems seem to have occurred by doing this.
    Note: 20090224 George Petrakis - Have added logic for waypoints. Currently for waypoints, validation occurs, but no 
    messages are displayed to the end-user, if there is a failure. Therefore only when 
    isViaClick is boolean, true represents a call from a button click event, false represents a call from elsewhere, e.g. firing of a drop-down list selection change.
