#include <smart_interp.h>
This class can semi-intelligently handle arrays which are not-well formed outside the interpolation region. In particular, if an initial interpolation or derivative calculation fails, the arrays are searched for the largest neighborhood around the point x
for which an interpolation or differentiation will likely produce a finite result.
