[Coin-ipopt] Changes to MATLAB interface for IPOPT

[Peter Carbonetto]

I'm announcing a few small changes to the MATLAB interface for IPOPT 
(see Ipopt/contrib/MatlabInterface):

1. You can now input your own initial values for the Lagrange multipliers.
2. You can now access the Lagrange multipliers obtained at the stationary
    point to which IPOPT converges.
3. You can also get the number of iterations that IPOPT needed to
    converge to the local solution.

See the documentation both on the IPOPT wiki and the 
Ipopt/contrib/MatlabInterface/readme.html file in the TAR archive for more 
information.
