Another Newbie question :)

[Patty Fong]

I seem to understand the basic idea behind the fold function, i think but do 
not seem to be able to write them myself. My understanding is that it works 
by replacing every constructor with a fold ?

Could anyone please point me in the direction of a suitable resource of 
attempt to explain this to me :)

Cheers,
Paty
