Detailed Description

Class for calculating Kernel Lobatto basis functions.

This class extends LegendrePolynomial to provide Kernel Lobatto polynomial evaluation capabilities. Kernel Lobatto polynomials are a specialized variant that may be used for specific boundary conditions or integration schemes.
