The GPS Coordinates will be in one of the 4 input formats if no 
validation error is shown to the user.  Feel free to use any of the 
output formats you choose.

When saving the data you will need a list of Rational.  It is easy to 
get this from the "DEG-:" output format. (I already wrote some code to 
do this.)

I haven't looked at adding another output format to conv_lat_lon.  
Perhaps we should keep this within the gramplet for now.
