added function to create file names

took Rachel’s file, added functionality to create json file and a
function to name the file with variables
Removed conflicting files
Changed a lot! This writes separate files for each year wight he
headlines for that year (without repeats, I think). Threw in a regular
expression that I didn’t end up using. I currently have it set to print
out only a couple of ears so that it doesn’t write too many files.
