create a currentStats_exec.R script

[jonathancallahan]

The local_executables/EXAMPLE_exec.R script is an example of a "stand-alone executable script". This can be run from inside RStudio or at the command line by passing in various arguments.

After we create a script that generates the specific set of status data we want, we need to wrap it with all the _exec.R features so it can be run from the command line.

Then we can set it up as a "cron job" to run automatically in the background.
