Reads ABIF sanger sequencing data files. ABIF files are a proprietary binary
sanger sequencing chromatogram data file created by Applied Biosystems (see
http://home.appliedbiosystems.com/support/software_community/
ABIF_File_Format.pdf). The file is read and parsed into an
abif class object. This method is based on the read.abif
function in the seqinr package available on CRAN.
