Setting up a local DNS server with bind on OSX Mavericks

This is really just an approach for locally testing DNS changes, which can easily be done with a HOSTS file if the change involves an IP address, but gets a bit trickier when things like CNAMEs are involved. This is only meant to test locally off a single machine.

1. Install bind using homebrew

   brew install bind

2. Follow the installation steps to start up bind
