TNC: A Python interface to the TNC non-linear optimizer

TNC is a non-linear optimizer. To use it, you must provide a function to minimize. The function must take one argument: the list of coordinates where to evaluate the function; and it must return either a tuple, whose first element is the value of the function, and whose second argument is the gradient of the function (as a list of values); or None, to abort the minimization.
