The only stage where parallelism changes the adaptive time
stepping is when some inner products on the saturation and
pressure are computed.
This commit makes this part parallel by added an additonal boost::any
parameter to the time stepping and the controller. Per default this
is empty. In a parallel run it contains a ParallelIstlInformation object
encapsulating the information about the parallelisation. This then used
to compute the parallel inner product.
-max time step parameter
PIDTimeStepControl --> TimeStepControl:
- added simple iteration count time step control
- bug fix in PIDAndIterationCountTimeStepControl
AdaptiveTimeStepping: apply the above changes.
