[fprint] Great job!

[Mark Vytlacil]

I had just about given up hope that you would get past the export hurdle. It 
works great! I am using the microsoft reader. I am still getting used to 
putting my finger on the reader in a consistant manner. It helps to press a 
little. A configuration option for matching threshold might be nice; maybe 
in /etc/fprint. I put 3 copies of the fprint line in my pam file so that it 
gives me 3 chances to match.
