Build component to display the generated Markdown "tree printout"

[nchaloult]

A cornerstone feature of our application is a display for the "tree printout" that our app generates once a user provides a public GitHub repo URL.

Living Feature Checklist

I just remembered checklists in Markdown (even though I learned about them like 2 days ago during the "intro to GitHub" course that we took through TalentLMS), and now I found an excuse to use them 😃😜

• [x] Clean and readable "box" to display the generated tree
  • Front and center on the web page
• [x] "Copy to clipboard" button

Stretch Goals

• [ ] "Delete" button next to each line of the generated tree
  • If users don't want to include particular folders in the generated output that they slap on their project's README, they should be able to conveniently remove those lines from the generated output
• [ ] "Undo" functionality (if we implement the "delete" buttons)

At this point in the life of the project, the team decided that we won't have time to work on the stretch goals that were outlined in this issue. For the purposes of a hackathon project, the "tree printout" component's functionality is complete.
