[Bioperl-l] Taxonomy DB problem

Chris,
There are a few things wrong with the original script, so I'll fix them.
Basically, it makes the assumption that every ID in the original list is
found. The problem: eutils only reports back data it finds, silently
discarding IDs that don't match. So, using the original ID list when
building the hashes needs a bit more error checking.
Here's the revised script that works for me.
https://gist.github.com/f5db90a432fed68548d4
I'm also adding a check to ensure all IDs are defined prior to adding
them to the param string, just in case.
