Add graphical user interface for RStudio for packaging

[nuest]

RStudio has some nice ways to create a GUI (when package is used in RStudio presumably), so when needing user input this could be handy

See RStudio Add-inns: https://rstudio.github.io/rstudioaddins/

Hi @nuest - a group of us at ropensci oz unconference 2018 are going start hacking at a few issues on containerit, including this one! Our fork and issue branch is here: https://github.com/ropenscilabs/containerit/tree/Issue27_GUI. Let us know if you have any thoughts on this one.

Thakns @smwindecker ! That's great! Apologies for not getting back to you sooner. I will take a look soon. I guess master...ropenscilabs:master replaces #134 ?

Hey @nuest, I ended up working on a separate part of this project. Can't tag Elise Gould for some reason but she led this team so I'll nudge her in person to check your question.

Thanks for alerting me to this @smwindecker. That's correct, @nuest!

Investigating https://github.com/o2r-project/containerit/pull/146/files now.

@egouldo Thank you so much for your awesome contribution, and my sincere apologies it took me that long to get around and take a look. As you might see in the history, I didn't do any development on this package for quite a while, but now I'm pushing some things forward, including your UI!

I don't know how to repay your efforts, but do let me know if you have an idea. What I can do is give some feedback on your code @clairemiller (can't tag Mark ☹️ )

During my review of the code, I made some style changes and wording changes, and refactoring, see nuest@5d54092

• I am not an experiences Shiny/Addin developer, so for easier understandability (thinking about future me) I used explicit labels for the functions
• Capitalising Dockerfile
• Spaces around =, space after , in function argument list, use <- for object assignments and = for argument assignments
• use the same type of quote character (not mixing " and ')
• added a file common.R to have one share place to reduce duplication of code statements, e.g. the volumes <- definition for file opening dialogs.
• some aligning of function names (e.g. in addin.R)
• use basename to get directory name instead of regex
• Put shiny::stopApp() at the same spot in all event functions
• rename script files

I created an issue to develop the UI further: #147 Let me know what you think!

Again: 👍 💯 ❤️ Thank you! 🚀
