0000545: IMPLEMENTED: interface to stop running nonlinear optimizer
Previously it was impossible to stop running optimizer from its internals. Say, after you started LBFGS optimizer, you have no other choice except for waiting for one of the stopping criteria being met.

Now, CG, LBFGS, BLEIC and LM optimizers allow user to terminate optimization process from user-specified callback function. Family of functions called like MinLBFGSRequestTermination() tells optimizer to smoothly stop at the current point and return control back to user.
