IInterpolator

This class extends piecewise linear interpolation to handle various coordinate systems and periodic/circular data. Transformations are applied at construction time, and evaluation uses standard piecewise linear logic in the transformed space.

Coordinate Transformations: The curve supports log, logit, and decibel transformations on both axes. These transformations are useful for data that varies exponentially or sigmoidally. Transformations are applied once during construction and inverted during evaluation.

Periodic Curves: For periodic data, the curve wraps x-values modulo the specified period. Query points outside the initial range are automatically mapped back into range. The curve is seamless at the period boundaries.

Circular/Angular Data: For angular data (e.g., compass headings), the curve unwraps angles during construction to avoid discontinuities, then wraps the interpolated result back to the standard range. This produces smooth interpolation across angle wraparound boundaries (e.g., 359° to 1°).

This class is typically constructed via factory methods in the Interpolation class such as LogLinearCurve(Double[], Double[]), PeriodicLinearCurve(Double[], Double[], Double), and CircularLinearCurve(Double[], Double[], Boolean) rather than direct instantiation.
