[FX.php List] How to use SetFMGlobal

[malcolm at notyourhomework.net]

OK, I can do that.

1. use postcode to search
2. get results
3. if there is a optional range present, do the maths and generate a  
new search
4. get results
5. print the list

I was allured by the prospect of FX being able to handle it all in one  
request.
