Detailed Description

Implements TGA algorithm to update solution to heat equation.

The LevelTGA class implements the Runge-Kutta-based approach to solving the heat equation due to Twizell, Gumel, and Arigu.

computes time-centered diffusive term for explicit updating

compute time-centered L(phi) for use in subsequent update operations. In this case, we do solve for phiNew, then subtract source and old phi back out to get L(phi).
