[SciPy-dev] TNC constrained optimizer now in SciPy

[Travis Oliphant]

Thanks again to Jean-Sebastian for another constrained optimization code. 

I've added his TNC package to SciPy.

I made a couple of changes to the interface to make it consistent with 
the rest of scipy.optimize.  Other than that it's pretty much his code.

This code even runs very quickly for the simple unconstrained cases I 
tried.

So, it looks like now we have two decent constrained optimization codes 
in SciPy.

Fantastic!!  Play away.
