Create an algorithm to save a series of contour plots as a video

[DanNixon]

This issue was originally TRAC 11430

Given some matrix workspaces (as a WorkspaceGroup) create a contour plot for each and output them as a video file with a given delay between each frame.

There should be support for adding log values as annotations to the frames, putting several plots side by side and normalising the data to the first dataset in the group.

For now this will just be a script.

An initial version of the script is here: https://github.com/mantidproject/scripts/blob/master/development/inelastic/colour_plot_timelapse.py

This does everything (with the exception of side by side plots) that the script needs to.

It can be tested using the data in Babylon5/DanNixon/osiris_scan

At the moment the script runs, but does not appear to create a video (at least on windows).

This needs better documentation for setting up an environment where it will work.

For example is it linux only? Can it be run on windows if ffmepg is installed, and where does it need to be installed?
