Add brew --caskroom to print the homebrew caskroom path.

Thoughts on merging this command with brew --cellar? brew --cellar atom would output the caskroom path of atom.

--cellar) echo "$HOMEBREW_CELLAR"; exit 0 ;;

would be great to add.

I think they should probably be kept separate because they are in different locations.

This is worth keeping but punting to Bash if possible, too.

[whoiswillma]

Already implemented this, but why punt this to bash? Is it for speed?

[MikeMcQuaid]

Yeh, it's dramatically faster.
