Thanks for the great answer Hilmar!
I would prefer to have some kind of a check if the user wishes so. For 
example Entrezgene file contains some HTML tags in some entries species 
names which is good to know.
I will put an option -validate_species in the constructor to turn the 
check on and off. Maybe a species filter can be of some use as well. 
though you can just select the correct file from the NCBI site....
Thanks again!
Stefan
