Completed but hoping to tweak some more

After our extensive coverage on sinatra and the pg gems, this assignment didn't seem so daunting. I took my time with minor format changes / routing decisions. No serious difficulties encountered other than lazy coding (making small spelling errors). 

This was the first homework assignment where I actually got into some code flow (writing without reference) and I'm really excited about it!!

I hope to add a simple edit to the boolean values on my :completed values. If the to do is completed, I'd like it to say [Completed on -date-] or for false it would say (instead of "f") [Working on it] or if it was overdue (probably going too far here) it would turn the text red. 

I'm also interested in moving the completed todo's to an entirely different page once they're completed. :+1:
