Beginner tutorial problems

[gcapes]

1. Doesn't leave the user with a working set up.
   There are several missing details e.g. "configure matflow" step doesn't explain how to set up matflow environments, which are needed for any workflow to run.

2. No example workflow is given to run. Step 4 says to define a workflow, but gives no clues how to do that.
   Maybe we could use a hello.yaml here?

3. Step 6 talks about matflow logs <workflow_file>. I can't find the matflow logs command. Does it exist?

4. Location of the workflow output directory is incorrect:

   you can view the results in the output directory specified in the workflow file

   The workflow directory is automatically named, or named as specified as a command line argument at submission

5. Two step 6s

Overall I'm not sure what this tutorial intends to add beyond what is covered in the "installation" and early parts of the "getting started" pages.
