This function checks if the query is valid or not.
It can be used to introduce arbitrary constrains. Since the Gaussian process assumes smoothness, constrains are managed by the inner optimizer (e.g.:DIRECT), being highly time consuming. If the constrain is very tricky, DIRECT will need much more function evaluations.
Note: This function is experimental. Thus it is not made pure virtual. Using it is completely optional.
