[CIG-SHORT] pylith time stepping

[Christopher DiCaprio]

Hi,

It's not clear to me what is supported for the nonuniform, automatic  
time stepping. The release notes for 1.3.0 say "For the current bulk  
constitutive models, the automatically determined time step is  
independent of the deformation rate, so it is uniform."

The release notes for 1.3.1 don't mention time stepping, but the  
manual implies that there is support for non-uniform time steps.

One other thing: when using nonuniform, automatic time stepping, the  
*_info.vtk files are overwritten with what should go in the  
*_t0000.vtk files. This doesn't happen when using user-specified time  
stepping.

Thanks,
Chris
