use_derivatives

Use derivative data to construct surrogate models

## Specification

Alias: none

Argument(s): none

Default: use function values only

## Description

The `use_derivatives` flag specifies that any available derivative information should be used in global approximation builds, for those global surrogate types that support it (currently, polynomial regression and the Surfpack Gaussian process).

However, it's use with Surfpack Gaussian process is not recommended.
