    @brief      A quote state returns a quoted string token from a reader
    @details    This state will collect characters until it sees a match to the character that the tokenizer used to switch to this state. For example, if a tokenizer uses a double- quote character to enter this state, then <tt>-nextToken</tt> will search for another double-quote until it finds one or finds the end of the reader.
