Detailed Description

Performs a barycentric interpolation with an order in a range fixed at construction; this class can be chosen via the options factory mechanism as a possible SpanInterpolator.

Details

This will call a barycentric interpolation on a fixed minimum length, so that buffers that adjust length based on required_points_before_and_after() can be forced to use an interpolator of a target order.
