Explain "@" in readme

[theoephraim]

I love the simplicity of jazz, but I'm sure you know, the readme could use a bit of help.

The thing that I was totally confused about was it was mentioned nowhere that in order to call a function other than a filter function, that you needed to include an "@". This is also skipped over in your tutorial but I just happened to catch it.

Plus, you should at least include a link to your tutorial (http://tomlee.co/2011/04/intro-to-jazz-templates-for-nodejs/)

ALSO:
I've been considering putting together a helper module that works as a manager for these templates as I have done in my own projects. But before I do it, is there another templating module that has replaced this one in your new projects?

Hey @theoephraim -- sorry for the (very!) tardy response. You'll notice @dbrain just updated the README to document a few more things like synchronous function calls. Pull requests with improved documentation will likely be met with much love and appreciation.

Not sure what you mean by a "helper module" here, but I'm sure the guys are open to hearing more about it.
