This includes Week 6 homework

I renamed the html_render.py file from the one I was noting down during optional class, so that's the reason for all the deletions and insertions. I tried to create it without looking at the notes as much as possible, but classes are pretty confusing, so a lot of it is very similar. 
did this work?

you wouldn't usually use map for a function that required user input.

this looks like it would apply the renamer function to each letter in the filename.
