Sparse Matrix Problems

Choose to answer the question about sparsity of matrices consistently....otherwise funny things can happen. For instance, I tried to set up a coupled 2/3D mechanics problem (to be committed into main CMISS repository soon). I chose to have non-sparse matrices when asked in the ipequa files for the 3D and 2D problems. Then, I chose to have a sparse matrix in the solution procedure file - irsolv. So when I output the global stiffness matrix to a file, I only got a cut down version of the matrix.
