def __ne__(self, read):
return (Sequence.__ne__(self, read) or<EOL>self.seq_qual != read.seq_qual)<EOL>
determine whether two fastqSequence objects are not equal. They are
considered unequal if any of their sequence data (name, nuc. sequence)
does not match, or if their quality data does not match.

:param seq: the other sequence to compare against.
:return: True if this sequence is not equal to seq, else False.
