Update WDL tutorials with new files & URL links about wdl

[vdauwera]

While you're at it, could you please also address https://github.com/broadinstitute/dsde-docs/issues/1153? Thanks!

Ok, I uploaded a WDL and JSON set and created two pull-requests related to these uploads.

Before I upload the other sets, is it possible to have these as one pull-request? If I can help it, I don't want to create more review work for folks.

[sooheelee]

I have answered my own question. I need to clone master and create my own branch.

@vdauwera Who can give me permission to push?

Did you handle setting up the folders for tour own files then? I thought I would be handling uploading your files as a part of my pull request, but I can take it off my list if you would rather do it yourself.

[sooheelee]

I gotta learn Kate. I'll be uploading regularly and can't be bugging you each time. Maybe modify your list to "Help teach Soo Hee upload and put in a pull request"?

[knoblett]

Absolutely fine; it's not terribly difficult once you get the hang of what commands to enter when. I can send you my step-by-step process if you'd like, or I can teach you in person when you are ready to merge.

[sooheelee]

I think I have the basics down. Might be asking questions later on.

[knoblett]

No problem!

Closing this issue now, as I forgot that I had it associated with the PR that is now merged.
