Detailed Description

The ndg_tu_alibdi class applies limiters to a dataset This is my attempt at implementation of DG limiter presented by Tu and Alibadi for Warpxm It is the "2D Limiter" presented in "Nodal Discontinuous Galerki Methods" by by Hesthaven and Warbarton.

The DG formulation in that book is rather different from WARPXM so we'll see how this goes... The paper is: A SLOPE LIMITING PROCEDURE IN DISCONTINUOUS GALERKIN FINITE ELEMENT METHODS FOR GAS DYNAMICS APPLICATIONS. SHUANGZHANG TU AND SHAHROUZ ALIBADI INTERNATIONAL JOURNAL OF NUMERICAL ANALYSIS AND MODELING, Volume 2, Number 2, Pages 163

This isn't even implemented yet. I skipped this instead for Scott Moe's limiter
