@param [Hash] opts Middleware options

@option opts [String] :stylesheets_path (env)

Stylesheets root path or app's public directory where the stylesheets are to be found

@option opts [Regexp, Array, String] :paths

Limit processing to the passed absolute paths
Can be an array of strings or regular expressions, a single string or regular expression
If not passed will process output for every path.
Regexps and strings must comence with '/'

@option opts [Boolean] :pseudo (false)

If set to true will inline style for pseudo classes according to the W3C specification:
http://www.w3.org/TR/css-style-attr.
Should probably be left as false because browsers don't seem to comply with the specification for pseudo class style in the style attribute.
