Provides a set of classes for creating objects that interpolate between a list of positions in various (useful) ways.
All interpolators are concrete sub-classes of {@link uk.ac.starlink.diva.interp.Interpolator}. To use these either supply arrays of positions and values to the appropriate constructor, or use the {@link uk.ac.starlink.diva.interp.Interpolator#setCoords} method. The interpolated values can then be queried using the {@link uk.ac.starlink.diva.interp.Interpolator#interpolate} method, supplying the position the value is required for.
Interpolators can be used together with the {@link uk.ac.starlink.diva.geom.InterpolatedCurve2D} class to display themselves as Java2D graphics objects.
