I am trying to create an instance of fd class using this call 
FiniteDifferenceModel<CrankNicolson<TridiagonalOperator> >


Obviously this is not possible since the constructor is (const 
operator_type& L, const bc_set& bcs, const std::vector<Time>& 
stoppingTimes = std::vector<Time>())

What I understand is stoppingTimes is an array for maturities. In case 
of plain vanilla or simple up out call it might be single maturity say 1 
year. So that information can be easily sent through. The other two 
fields operator_type and bc_set are wierdos. Tough to get at first 
glance :) .

Since the documentation is obsolete I tried opening up lots of header 
files and lots of cpp files to wrap around the code in my head. (Frankly 
speaking I come from C Linux Kernel Coding world so C++ is a mess to 
me!). Anyway if someone has followed my problem till this point do read on!

Again operator_type and bc_set are members of Evolver class which can be 
something like CrankNicolson. So I rushed to it's header file 
cranknicolson.hpp to get some clues. But still I can't figure out what's 
operator_type or bc_set. My best guess was TridiagonalOperator class, 
but still that didn't work.

Since most of the FD engines given in the sample examples are of useless 
from trading perspective I was creating more practicle ones which can be 
used more from static hedging perspective. So it would be really helpful 
if someone can help me understand at least how to initialize the generic 
FiniteDifferenceModel class.

I guess I should send this to dev's list, but well will wait...if I 
don't get the reply I will forward coz i guess questions are not that 
simple ;)
