1) First of all, can you describe in a  bit more detailed way the usage of
AppCtx class of matfree.py module to solve ODE systems
(determined as in rober.py), without jacobian initialisation, in other words
how can change rober.py to solve this issue?

2) Does THETA integration implement time step adaptation?

3) Suppose i have a large ODE system, how can i implement multiprocessor
(parallel) integration in a way similar with those (function definition and
plotting) in rober.py?
