Simulations run for longer at smaller time steps.

The interfaces were breaking down near the end of simulations with
finer grid sizes. This may have been due to the time step becoming too
large when the deposition shuts down. This change allows a maximum
time step of 1 and goes out to 7000s.
Launch new simulations that save all the field data.
Need quotes around argument with spaces.
Reconfigure viewers for improved movie imgaes.
Refactor viewers in preparation for 2 paned movie.

Also run a new simulation saving `iterfaceTheta`.
Update viewers for new movie.

Refactor viewers for new movie and changing the name of the notebook.
Forgot baseViewer.py in last commit.
Remove convergence.ipynb.
