Adds initializer, takes in cannes year for scraping
Working version of scraping for movie URLs

 - takes in the year in class initializer
 - generates URL for each Cannes selection year
 - selection_links method parses and finds URL of each movie
   that was selected in that year
Selects movie title and year

 - title: pulls from <title> tag, removes "Cannes Film Festival" by splitting
         takes the first element in array, which is the actual movie title
         then removes ALL CAPS and capitalizes every word in movie title
 - year: finds <dt> element, which has title Year:
         takes the next element, which will be the actual year
         converts to integer, so that is correct data type in movies table
Working Version - scrapes 1 movie from Cannes website

 - uses Xpath and CSS selectors to pull in title, year,
   synopsis, country produced, thumbnail url
 - assigns arbitrary user_id, since not a user submitting
Creates cannes table

 - stores URL to the film on cannes website
 - adds a cannes_id to movies table
Removes movie_id from cannes table, creates method to save to db

 - double dependency, removes movie_id foreign key from cannes table
 - creates method to save cannes info to db
Attempts to capitalize title, capitalize method not working with parentheses
Move movie title parsing to its own method

 - changing ALL CAPS to capitalize needed more parseing
 - needed to write additional code
   to ensure the first letter in a word right after a parens
   would be capitalized
Adds lots of puts statements to view progress when scraping
Adds get_page method to sleep in between GET requests
Not working, committing and will clean up
Updates xpath for movie thumbnail, was unable to save movie bc invalid url
Scraping cannes website works
