Example proposal

@johanbrook: I just found that those lines here

meteor-emails/example/server/server.js

Lines 4 to 6 in 7c98ce5

	if (!process.env.MAIL_URL) {
	process.env.MAIL_URL = Meteor.settings.MAIL_URL;
	}

lead to a wrong behaviour in development mode: it keeps Mail.send() from printing the mails output to the console, if NO MAIL_URL has been set. I had to remove this line to see the output. Maybe you can remove it from the example? Or is there any real feature this is giving?
