install

[kellijohnson-NOAA]

Change the install script to be part of the workshop script, where they run it first. Having two scripts is confusing. Also, change where the script automatically downloads the workshop folder, unzips it, and sets their working directory to where they just unzipped. Additionally, it would be nice if the install instructions were the same as what is found on the readme because people tended to go there first, rather than following the instructions.
