Change figures/ to fig/

[jdblischak]

The subdirectory with images is currently figures/. This needs to be changed to fig/. Also the knitr chunk options at the beginning of each file needs to be updated to reflect this, e.g. opts_chunk$set(fig.path = "figure/02-func-R-") would be changed to opts_chunk$set(fig.path = "fig/02-func-R-"). See Lesson Layout for more information.

Shouldn't this be closed by #23 ?

I also wanted to have a default option. Thus if someone created a new file and didn't specifically label the output figures, they would still be sent to fig/.

OK, I made the change to tools/chunk-options.R in lesson template (PR), so this will be fixed once we merge the core branch of lesson-template into this repo. Thanks for the reminder, @jameshiebert.
