Add dockerfile for metacell analysis #11

	# This is a workflow to run the metacells module
	#
	# Analysis modules are run based on three triggers:
	# - Manual trigger
	# - On pull requests where code in the module has changed
	# - As a reusable workflow called from a separate workflow which periodically runs all modules
	#
	# At initialization, only the manual trigger is active
