/**
   This method is what performs the model -> part number mapping
   Fujitsu requested. I have made it general enough to function 
   exactly as-is for the webview content, as well as for the 
   stand alone web site. 

   It would be nice to consider some kind of a way to avoid all 
   these IF checks. What I really would like is a hash key'd on 
   the model, with the part numbers stored as the value, as a list. 
   JSON would probably be good for this. If I created it in a very
   readable way, our customers could just approve the JSON file. 
 
   Then, I could write a routine which takes a selection box and a 
   list, and populates the selection box with the values from the list.

   This will be for version 2.0.
