Feature Request: isEmpty

[donaldpipowitch]

It would be nice, if fs-extra would have a function which checks, if a directory is empty.

What's the use case?

[donaldpipowitch]

Currently writing some sort of documentation linter which checks, if the examples/ directory in our projects is empty. Basically this is a more powerful fs.exists in my use case. (Thinking of it, isEmpty could also check if a file is empty, if it isn't a directory.)

A requirement for isEmpty would be to automatically ignore meta files like .DS_STORE on Mac OS X.

Example:

Wouldn't be opposed to an isEmpty method with a filter option, but ignoring meta files would be rather unexpected. Should be in a separate lib IMO.

@jprichardson Reopen if you disagree.
