install_user_app() code

[chasemc]

Here is where it breaks:

` my_package_name <- electricShine::install_user_app(library_path = library_path , repo_location = "local", repo = local_package_path, repos = cran_like_url, package_install_opts = package_install_opts) }

Transfer icons if present -----------------------------------------------

electron_build_resources <- system.file("extdata", "icon", package = my_package_name, lib.loc = library_path)`

Because electricShine::install_user_app can only return a NULL as it just gives the result of readLines() on a newly created tempfile?

I'm happy to help make this thing a reality, but, the code in install_user_app is really confusing. Like, are all of the environment variables just being used to prevent you from having to pass variables between functions?

Code needs better documentation.

The variables are the only way to make R install packages in the correct location
