--ignore flag to ignore files under a path

[sungwoncho]

Allows one to ignore files under a given path

e.g.

mstat --ignore packages/bootstrap/*
mstat --ignore packages/bootstrap/

Feedbacks are welcome.

+1 to this. I like the how the metrics are shown, but unfortunately, it gets skewed if we have a lot of 3rd party lib files, which should ideally be ignored. Can we have the above feature?

A workaround is to add the directories to the .gitignore file and then take a count.
