Make dirty duck available from pip-installed triage

[shaycrk]

It seems like a typical user would want to be able to run triage just from the pip installed version and the tutorial should probably support this, without requiring a clone of the github repo. I'm wondering if we could integrate the tutorial shell script with the triage CLI, allowing a user to run something like:

triage tutorial start

Is there anything that would make this particularly challenging or problematic?

Totally agree, actually related to #749

Nothing problematic, the only stopper is that I need to read the argcmdr docs :)
