An assembler for the purkinje part of the left hand side matrix of the monodomain-purkinje linear system. The full LHS matrix will look like (written in block form, although the code uses striping) [ chi C M/dt + K 0 ] [ 0 chi' C' M'/dt + K' ] where the top left block is the standard LHS matrix in a monodomain problem, and the bottom right block is the equivalent from integrals over cable elements.
This class assembles the matrix [ 0 0 ] [ 0 chi' C' M'/dt + K' ] The entries in this right-hand block are only non-zero on Purkinje nodes

Myocardium and purkinje potentials exist for each node, so PROBLEM_DIM=2.
