#2: Problem with different interfaces for Bonmin and Ipopt function
get_starting_point

 I am using Bonmin to perform mixed integer optimization, but I wanted to
 check my derivatives with Ipopt.  Ipopt and Bonmin have slightly different
 interfaces for the function get_starting_point.  When I had the Bonmin
 convection implemented (does not use init_z), but not the Ipopt one, Ipopt
 will call get_bounds_info(...) instead of get_starting_point(...).  This
 is VERY confusing. I spent 2 days trying to figure out why the inputs to
 get_bounds_info were strange, and why I kept getting segmentation faults.

 I would recommend that the two interfaces be reconciled, so that this type
 of error could be avoided in the future.

 thanks,
