Chicken etc. genomes

[mccalluc]

It looks like we're hard-coded for hg19 right now:

docker_igv_js/context/on_startup.py

Lines 7 to 14 in a0a8680

	with open("data/input.json") as f:
	config_data = json.loads(f.read())
	tracks = []
	assembly = "hg19"
	url_base = "https://s3.amazonaws.com/data.cloud.refinery-platform.org/data/igv-reference/{}/".format(
	assembly
	)

but it shouldn't be hard to

• upload genome reference files to s3
• update this to actually read the input.json
