Added redirection from herokuapp site

Not sure what the best routing path to put in app.get(), so feedback on that would be nice. 
Aside from that, this seems to work on my localhost:3000. Took me a while to figure this out because chrome browser caches 301 redirects, so I spent a lot of time figuring out why my redirects were going to some change in the code that I had put in previously and not my current redirected site. 

Anyway, hope this works. Please let me know where I can improve the code; I'm relatively new to this. 

Thanks!
