Using custom resources and installing without databases

[rickymagner]

Hi, I was wondering if it's possible to install the hgvs package without needing the SQL/database dependencies, and possibly being able to bring your own resources to use (e.g. your own gencode table)? I wanted to use the package in a cloud environment where installing those dependencies may be difficult, so it would be great if I could just install the part used for parsing/normalizing/etc. and then have a way to provide my own files for the reference, gene boundaries, etc.
