 // TODO(terry): Add optimizing phase to remove duplicated selectors in the same
 //              selector group (e.g., .btn, .btn { color: red; }).  Also, look
 //              at simplifying selectors expressions too (much harder).
 // TODO(terry): Detect invalid directive usage.  All @imports must occur before
