proctor

#### ~ Watch over your javascripts.

Proctor lets you watch over your javascript file with a function as an export.
For instance(and as a real-world example), I can have a server file like this:

``js
// server.js
var http = require('http');

var server = http.createServer(function (req, res) {
res.writeHead(200, {'Content-Type': 'text/plain'});
res.end('Hello, World!\n');
});

exports.startServer = function (config) {
server.listen(config.port);
console.log('Server running at ' + config.port);
};
`

Notice that this file only exports a startServer function,
so it is impossible to develop with something like forever.
Instead, I can use Proctor:

`js
// run.js
var Proctor = require('proctor');

var runner = new Proctor({
file: 'server.js',
fn: 'startServer',
restart: true,
config: {
port: 3333
}
});

runner.start();
`

Now when I run node run.js`, Proctor will spin up a separate child process in which to run my file,
and reload it automatically when it is changed.
This is perfect for build system support, especially if you're developing a web app.
