Implementation of analytically derived Jacobian
Implementation of analytically derived Jacobian

Jacobian method can be used with or without inline. May be some
slight code redundancy in a few spots since the Jacobian formulation
is similar to formulation of the RHS. I consolidated a few spots but
left some sections more transparently duplicated because it seemed more
readable that way.
