Looks OK to me, but I think @aarontp should approve too.

[aarontp]

Cool! Should we maybe have this generate the Task template at the same time?

@kiddinn: You've probably seen this already, but here's the docs on how to create a Job/Task right now:
https://github.com/google/turbinia/blob/master/docs/developing-new-tasks.md

For most of the current Jobs and Tasks, there is a 1:1 Job:Task mapping (e.g. 1 PlasoJob -> 1 PlasoTask), but we're starting to create and plan for more complex Jobs/Tasks that split up the Jobs into multiple Tasks. There's a little more documentation on Jobs vs. Tasks here: https://github.com/google/turbinia/blob/master/docs/how-it-works.md

wIll add a task file generation to this scaffolder as well

[kiddinn]

I've asked @aarontp to take another look as well, but I added the task generation and renamed files. Ready for another round.

[kiddinn]

need to rebase and add minor corrections after the push of init file changes got pushed in

[kiddinn]

again, a bunch of other files got mangled in, closing this PR and opening a new one
