Example for PYSEQM for free Google Collab cloud.

[tobigithub]

Hi,
I added an example for running PYSEQM in a free Google Collab notebook.
This might come in handy for people that do not have a computer, VM or GPU and want to play around. It
might also be useful for demo and teaching purposes. For example I could think about links to all the provided
PYSEQM tests from this repository running on a Google Collab notebook. Or the user picks the test number
and is then presented with an animation.

It basically runs the MD on the free Google Collab cloud and then visualizes the trajectory

1. Install PYSEQM from https://github.com/lanl/PYSEQM
2. Run initial test MD over 200 steps
3. Add Py3dmol
4. Render trajectory with py3dmol

The user can see the MD loop:

Very simple and effective.
