Detailed Description

Unlimited central-difference "limiter" — returns the arithmetic mean of the two one-sided slopes.

Diagnostic / comparison choice. NOT TVD: this can amplify oscillations at discontinuities. Useful as the smooth-end bracket against MinModLimiter to measure how much the TVD clipping contributes to time-stepper failures.
