add a check for the seq argument in seqrecord, to be a Seq object and not None

This patch adds a check for the seq argument in SeqRecord.
If seq is None (by default), it raises a ValueError Exception.
If it is a Seq objects, it saves it as self.seq.
If it is another kind of object (string, list, integer), it is converted to a
string, and then used to instantiate a seq object.
I thought that someone could use an integer (e.g.: 010100010101101) as a
sequence, and in this case, the integer is first converted to a string
(otherwise Seq() would return an error).

Please, take care with this patch: I have messed a bit with cvs and patches :(,
so, this patch contains also a doctest example that I have added for my self
(see bug report 2640).
