-----------------------------------+----------------------------------------
 By default, MoL initialises the RHS variables to zero before calling the
 CalcRHS routines. This is (a) superfluous in a well-written code, and (b)
 makes it impossible to re-use a RHS that has been calculated ahead of
 time, e.g. at the end of the previous time step.

 This patch adds a parameter to disable this behaviour.
