spanfill

<code>spanfill</code> generates points to approximate a space based on existing points.
These approximate points can be used to find local fill distance in the space or be used as candidate points in active learning.

Methods to generate a design in the input space that sequentially fills the output space of a black-box function. The output space-filling designs are helpful in inverse design or feature-based modeling problems.
