Use reval from Atom with convenient, customizable keybindings.
By default, atom-reval assumes your reval server is running on localhost,
port 3000.
To specify a different server, add a .revalrc file to your
project directory with the hostname and port separated by a colon, like this:
different.dev:3333
For a given file open in Atom, atom-reval will use the first .revalrc file
above it in the directory tree.
