Title: Adding caveats about setwd() to R novice lesson

For our final instructor training assignment, @sritchie73 and I have added some caveats about the use of `setwd()` in R scripts to the Best Practices section of the novice R lessons. We point out that `setwd()` can cause problems if others try to run your code on their machines, and we provide an example of the type of error that can result.
