Generates an input sample for a Monte Carlo estimation of global sensitivity indices. Used in
the `get_sensitivity()`

function. The total sample size will be \(N(d+2)\).

## Details

This function generates a Monte Carlo sample as described e.g. in the Global Sensitivity Analysis: The Primer book.
