Teddy Cleveland todo homework

Todo homework submission. I added a bit of styling and separated tasks on the main page by incomplete and completed. Checking the little box next to the task mean's you've completed it. There's still a bug that I've seen a few people having, where inputting a task with an apostrophe in it will create an error. Other than that it seems to work pretty well. I'd like to hear some feedback on this, because if I'm correct it's going to be one of our last heavy SQL projects. Thanks!
