Number of scalar response functions

## Specification

Alias: num_scalar_responses

Argument(s): INTEGER

## Description

This keyword describes the number of scalar response functions. It is meant to be used in conjunction with `field_responses`, which describes the number of field response functions. The total number of response functions, both scalar and field, is given by `response_functions`. If only scalar responses functions are specified, it is not necessary to specify the number of scalar terms explicitly: one can simply say `response_functions` = 5 and get 5 scalar responses. However, if there are three scalar responses and 2 field responses, then `response_functions` = 5 but `scalar_responses` = 3 and `field_responses` = 2.

This type of data set is used by uncertainty quantification methods, in which the effect of parameter uncertainty on response functions is quantified, and can also be used in parameter study and design of experiments methods (although these methods are not restricted to this data set), in which the effect of parameter variations on response functions is evaluated.
