Now that we have the basic ability for getting the weight of a media query, now it's time to bring that into CSSReader

1. import at-rule.js
2. import selector.js
3. calculate weight on a CSSRule
4. recursively walk up parentRule and add weight
5. Then produce total score on a CSSRule

Something that evaluates the whole stylesheet and determines the complexity of that stylesheet. it should produce data like:

• number of rulesets
• average complexity of a rule set
• number of media queries
• average complexity of a media query
• standard deviation?
• median complexity
• most commonly used selectors?

There should be code in cli.js that allows this to work as a CLI utility

It should take arguments like

• fileName or glob
• outputFileName

Need to use the css-reader class (or create a stylesheet class?) that is able to capture all media queries and determine their respective complexity.

We need probably a Media Query class that can calculate its own complexity. May need to rely on the CSSOM library.

It should recognize any @ rules, and determine the number of arguments it contains and produce a weight.
