Function for setting the solution map(reactant concentration, phi_s, phi_m, etc.).
First argument provide the map of solution variables. The second argument provide the name of the primary reactant. The final argument is the index of the solution map that the micro scale object should solve for, i.e. if the solution map contains arrays of quadrature solutions then the index corresponds to the quadrature point we are solving for
This function should be called immediatly before compute_current or compute_derivative_current.
