protein name alias service

[coreyflynn]

We need an API endpoint to serve as a protein name alias service. A user submits a partial or full protein name and all known matches or aliases to matches are returned.

To build this we need:

1. a full listing of the protein names we want to match against
2. a curated list of the protein aliases
3. a mongo collection to support efficient queries

Outstanding questions:

1. What gene symbols / protein names do we want to support?
2. What constitutes a valid alias? who curates them?
