class Sass::Selector::AbstractSequence

method that returns the string representation of the selector.
of object that respond to ‘#line=` and `#filename=`, as well as a `to_s`
All subclasses should implement a `members` method that returns an array
The abstract parent class of the various selector sequence classes.
