    _______________________________________________________

Details:

this patch adds the possibility to pass a function such that 

afun (x) = A * x

instead of the matrix A itself as the second input parameter to the bicgstab
function.

This makes bicgstab more compatible with matlab and more similar to other
iterative solvers.

I also added a couple of additional tests.
