[BioPython] Determining if GenBank record is circular

[Chris Lasher]

Is there a way to see if a sequence represented in a GenBank record is
circular in the information contained within a SeqRecord object created by
parsing the record with SeqIO? I couldn't find it in the annotations,
description, or format attributes of SeqRecord. An example file that I'm
looking for this in is
ftp://ftp.ncbi.nih.gov/genomes/Bacteria/Mesorhizobium_loti/NC_002678.gbk

Thanks,
Chris
