     Reference from Manual on ARKODE
     To choose an explicit table, set itable to a negative value. This automatically calls ARKStepSetExplicit(). However, if the problem is posed in explicit form, i.e. 𝑦 ̇ = 𝑓 (𝑡, 𝑦), then we recommend that the ERKStep time- stepper module be used instead of ARKStep.
     To select an implicit table, set etable to a negative value. This automatically calls ARKStepSetImplicit(). If both itable and etable are non-negative, then these should match an existing implicit/explicit pair, listed in the section Additive Butcher tables. This automatically calls ARKStepSetImEx().
