Example b2128: Small implicit 2d bidomain strip using Luo-Rudy current model

Example b2121 - bidomain This example solves the bidomain equations on a 2d domain. The equations are solved implicitly and the Luo Rudy ionic current model is used. Solution is by sparse LU factorisation and there are 8x8 grid points per element.
