Flags indicate whether it is time to execute slow RHS computation.
For instance, in the RK4-RK2 scheme, there are 4 substeps in total, but the RK2 RHS are only evaluated in the very first and in the very last step of the four substeps.

direct through the header file.
Add parameter to say if we want to use this function (by default we do, so nothing changes).

RK3. The optimized version of the TVD RK3 solver. Requires no scratch space so is about as efficient as ICN, but third order.
Generic method from a parameter table. By specifying the number of intermediate steps and the alpha and beta arrays, create your own method at parameter time. Not well (or at all) documented because it doesn't seem to work correctly at the moment.
Some tidying of extraneous code as well.

Only works with ICN or RK2 for now - in fact this commit may break the generic RK methods temporarily.
Note the documentation isn't quite right - there's no longer a seperate function for each different type...

Change the grid scalar used in the schedule.ccl from MoL2->MoL (necessary).

MoL provides generic integration methods for multiple thorns simultaneously. By providing a layer between the driver and evolution thorns, this should mean that some technical issues to do with mesh refinement can be ignored. It also allows you to choose different evolution methods (in time, at least). But the primary purpose is to unambiguously evolve models in different thorns at the same time.
This is version 2 - the one that will work with mesh refinement. It's a straight copy of HawkeCVS/Public/CactusMoL2/MoL2 and I haven't checked that it will work "as is" with the new name (one of the reasons it goes into Alpha).
At the moment the only evolution method guaranteed to work with mesh refinement is ICN, although RK2 should. The generic RK methods will do something that will be subtly wrong...
Note that the "old" way of registering variables (through the functions declared in header files) is still there. As soon as function aliasing settles down, this will be removed.
Also to be done:
Better documentation
Tidy up the code (especially the debugging statements)
Optimize
Add various useful time evolution methods.
