Class which specifies and solves a bidomain problem.
The solution vector is of the form: (V_1, phi_1, V_2, phi_2, ......, V_N, phi_N), where V_j is the voltage at node j and phi_j is the extracellular potential at node j.

pCellFactory | User defined cell factory which shows how the pde should create cells. |
hasBath | Whether the simulation has a bath (if this is true, all elements with attribute = 1 will be set to be bath elements (the rest should have attribute = 0)). |

Annotate bath nodes with the correct region code, if a bath is present. Will throw if mHasBath is set but no bath is present in the mesh.
