@option opts [String] :css_class (‘highlight’) @option opts [true/false] :line_numbers (false) @option opts [Rouge::CSSTheme] :inline_theme (nil) @option opts [true/false] :wrap (true)

Initialize with options.

If ‘:inline_theme` is given, then instead of rendering the tokens as <span> tags with CSS classes, the styles according to the given theme will be inlined in “style” attributes. This is useful for formats in which stylesheets are not available.

Content will be wrapped in a tag (‘div` if tableized, `pre` if not) with the given `:css_class` unless `:wrap` is set to `false`.
