Filtering on folder

[eXpire163]

It would be great to have a flag to limit the animation to only one folder or even a glob pattern

This would be usefull if you want to animate a repo with lots of generated code inside - in our case the documentation source i would like to show but hide the generated html directory

You can use --file-show-filter with a directory to only show files in that directory. E.g. --file-show-filter 'docs/'.
