[chef] FC001, attributes as strings vs symbols

[Joshua Timberman < >]

Ohai, Chefs!

We want to hear from you: which way of using node attributes do you prefer? 
Please take this single question survey:

http://www.surveygizmo.com/s3/1059291/FC001-Use-strings-in-preference-to-symbols-to-access-node-attributes

This is in response to a longer twitter discussion today on the subject. The 
survey will be left open for awhile, letting as many people as possible 
answer. We *really* value this feedback.

If you want an explanation of why this rule came about the way it did, and 
our rationale for preferring strings to symbols, see this issue in the 
Foodcritic project:

If you're going to be at the Chef summit next week, I'm happy to discuss this 
in greater detail, too :-).
