Small nitpick : stop codons are usually represented with "*", not "x"

That's actually fair. Note to self: add support for * in an amino sequence

I think I chose 'x' because '*' could have its own special meaning in the language, but I'd only been doing synbio for a month when I started the C# version of this project, so it might have been stylistic

Completely forgot about this, but I looked into it and it's an easy fix. GIL has support for non-canonical amino acids, so I'll just add a * key to the gilEncoding files so you can use either. This should be out with the next bool release!
