Time multiplexer filter
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
We should have a filter that multiplexes over time. It will take multiple inputs, each with the same geometry defined over different regions of time.
The time regions may overlap some. If this is the case, then the multiplexer should get the geometry from the input whos maximum time step is greater.
This filter will finally make it possible to load in simulation results from multiple restarts without combining the results together.
