mprove the way mapping between taxonomy names and id is done during IGC gene creation

The whole mapping between genus and phylum names are done locally to prevent the number of requests done during creation. This should improve the speed of creation. Still need to deal with #65 to be able to load IGC smoothly to the db.

Closes #66
