APPLgrid and HOPPET formulae

Hi, 

I've been using your tap for a while, and it's been really useful in reducing compatibility issues when putting together a MC toolchain. I've had a great deal of pain attempting to get things up and running on a Mac in the past, so it's a real help.
 
I thought formulae for HOPPET ( a DGLAP code by Salam and Rojo) and APPLgrid ( a set of MC event interpolating tools ) might be useful additions!

Cheers,
Nathan
