I'm writing to make a small contribution to the project.
Recently I made a small and simple code to evaluate the Hessian by 
finite differences. I did that code since I needed bonmin to solve  
integer problems and at that time, this feature was not available. I 
would like to know if you have interest in incorporating this code into 
Ipopt (around 30-40 lines). I think it is a good opportunity for people 
who wants to use bonmin and other codes. Although it is not very 
efficient it's working well.
