The idea behind this task would be to give an easy-to-understand/non-technical explanation of "Loop-invariant Code Motion" code optimization technique.

This explanation might be added to the rco's documentation page. A new topic named "Idea" must be added before the "Background" topic. In order to add it, the rco project must be forked, and the file https://github.com/jcrodriguez1989/rco/blob/master/vignettes/opt-loop-invariant.Rmd modified. This file is an R markdown file, it is recommended to install RStudio to easily compile this file.
