this really needs to be maestrowf>=1.1.5, which doesn't exist yet. so for now, we need to keep maestro install via GitHub develop

[ben-bay]

Addressed. Added in commented-out maestrowf>=1.1.5 to remind us to use it once it exists.

This line here is preventing the direct-from-github maestro being pulled into our zipped files:

merlin/setup.py

Line 77 in 65ae4e8

rl = [r for r in trl if "-e" not in r]

Perhaps we should remove the -e from the maestro install?

[lucpeterson]

Also this line should include the dev dependencies, so they can be installed via pip install merlin[dev]

merlin/setup.py

Line 37 in 65ae4e8

extras = ["mysql"]

I think we change it to ["mysql", "dev"] that'll grab all of the dev dependencies as an extra
