Routing Fixes

[karkir0003]

Right now, the About.js, Intro.js, Contact.js, Work.js articles are now in separate components under components/articles directory. However, when the user clicks on "About", "Intro", "Contact", the browser route is still the / route.

We should have a way to have the route in the URL change based on what article is clicked:

• If I click on About in the homepage, I should see /about route added and that maps to the About.js article content
• If I click on Intro in the homepage, I should see /intro route added and that maps to the Intro.js article content
• If I click on Contact in the homepage, I should see /contact route added and that maps to the Contact.js article content
• If I click on Work in the homepahe, I should see /work route added and that maps to the Work.js article content

For each of the above, there should also be the behavior of routing user to / (homepage route) if the "X" button is pressed on any of the 4 articles
