def __eq__(self, seq):
return (Sequence.__eq__(self, seq) and<EOL>self.seq_qual == seq.seq_qual)<EOL>
determine whether two fastqSequence objects are equal. To be equal, their
sequence data (name, nuc. sequence) must match, as well as their quality
data.

:param seq: the other sequence to compare against.
:return: True if this sequence is equal to seq, else False.
