 #### Ignoring module
 Sometimes you just want to ignore newer versions of some dependency for some reason. For example, you use `jquery v2` because of the old IE support and don't want `npm-upgrade` to suggest you updating it to `v3`. Or you use `some-funky-module@6.6.5` and know that the new version `6.6.6` contains a bug that breaks your app.
