/** A callback function (along the lines of Berkeley optimization repo), which is currently used in the optimization package.
* In the optimization package, it is used for passing values (newX, iteration, newObjectiveValue, newGradient) at every iteration and
* then you can do whatever you want with those values.
*
* One use case is to print the values in a file; another is do some sanity check etc.
