Task/rhornung67/rework lesson 04

[rhornung67]

Based on our meeting last week, this is what I had in mind for intro lesson 4. Note that it the README is about the same length as the original original, the work for the participants to do is similar (although it actually gives them a working version to look at), and it allows them to compare performance of sequential and OpenMP variants of the same kernel.

I like it! It gets participants running parallel programs sooner. I can also take a pass at removing the solution folder and moving the solution file to the same space as the exercise file after we merge this in.

I was thinking about doing that. I think it would be better to move the solution files up one level and remove the directory, since it would be easier to navigate. Also, I think we should build the solution files also so it's easier for participants to compare with their attempt.

This one is good to merge. Please review if you wish. Thank you.
