- Added `parse_model()` etc methods to parser.
- Made sure protocol is cloned in all simulations.
Protocols are not immutable and changes made after setting the protocol should not affect the simulation (or vice versa).
- Added a simulation that calculates the derivative of a state w.r.t. a parameter.
- Working on `MarkovModel` class.
- Added method to convert monodomain parameters to conductances to opencl simulation.
- Various small bugfixes.
