:clipboard: Additional detail

bioDBnet, created and maintained by the Advanced Biomedical Computing Center (ABCC), Frederick National Laboratory for Cancer Research (FNLCR), and National Cancer Institute at Frederick (NCI), is a useful tool for mapping identifiers from various biological, chemical, and pharmacological databases to identifiers in other databases.

I have implemented this module following style and functionality precedence from eutils.jl, as I wished to help maintain consistency between modules as much as possible.

This will be my first contribution to any public project, so I apologize for anything that has been done incorrectly.

Woo! Welcome to open source :-)

This is a very welcome contribution, but alas I'm not competent to review it.

@thatRichman - really sorry that this has languished for so long, especially seeing as how it's your first contribution :-(. Seems from your github activity that it didn't slow you down though - I'm glad for that. This package has not been super actively maintained, but I hope to turn that around. Are you willing to rebase this off the current master brach, then I can take a look?

If you're not sure how to rebase, I can help with that.

No worries at all! I've been plenty busy so I almost completely forgot about this. I'll make sure that it hasn't broken over the past year and rebase.

Fantastic! Ping me when it's done and I'll give it a review

I've confirmed everything still works and I think (hope) I rebased correctly! Happy to fix anything that may have been done incorrectly.
