[Dip] Problem running the GAP example

Hi Haroldo,

It's been a while since we worked with the applications. We have recently
been focused on using Dip as a generic decomposition-based MILP solver and
on its use through Dippy. It seems we have mucked up a few things with the
C++ application development. I am sorting it out now and will get back to
you soon.

Cheers,

Ted
