jetty 0.2.1

Improves error messages if the underlying Docker process throws an error.
Allows the user greater control over .Renviron and .Rprofile files:
- Allows users to explicitly ignore these files by setting the arguments r_profile = NULL or r_environ = NULL.
- Allows users to ignore these via environment variables or R options.

jetty 0.2.0

Execute an R script in a Docker container: jetty now supports executing an R script in a Docker container via the run_script() function. A particularly important argument is the context argument. This user should specify this as the filepath to a directory that serves as the script’s execution context. Specifically, this directory will be mounted to the Docker container and, as a result, this script will have access to all files/directories contained within the context. The script’s execution will fail if it attempts to interact with any files/directories outside the provided context directory. Note: this is a feature that is only designed to work well with MacOS and Linux and will most likely crap out if used on Windows.
