The domain we're going to build out is actors, movies, and roles. Actors can be in many movies and movies can have many actors.

Build out classes for actor, movie, and role. This is a many-to-many-through relationship.Role is the join class between actor and movie.

• a actor has many movies through role.
• a movie has many actors through role.
• A role belongs to one actor
• a role belongs to one movie

1. Actor - has the following attributes: first_name - string, last_name - string, age - integer
   • Actor#first_name, Actor#last_name, and Actor#age methods should all return the respective attributes
   • first_name and last_name cannot be changed once set, but age can be updated (since actor's never tell the truth about their age)
2. Actor.all - returns an array of all the actor objects that have been created
3. Actor#full_name - returns a string of a given actor's first and last names concatenated (e.g., "Tom Cruise")
4. Actor#movies - returns an array of movie object that the actor has acted in
5. Actor#credits - returns a hash where the keys are the movie title and the values are the name of the role the actor played in the movied - e.g.,

> tom_cruise.credits 
> # { 
> #  "Top Gun" => "Maverick", 
> #  "Mission Impossible" => "Ethan Hung",
> #  "The Mummy" => "The guy who kills the mummuy"
> # }

6. Actor.find_by_full_name(full_name) - accepts full_name as a string argument and returns a single instance of actor that has that name provided
7. Actor.no_younger_than(age) - accepts an integer age argument and returns an array of actor instances whose age is equal to or greater than the age argument passed in

1. Movie - has the following attributes: title - string, year - integer
   • Movie#title and Movie#year methods should all return the respective attributes
   • title and date can be changed once set
2. Movie.all - returns an array of all the movie objects in the collection
3. Movie#pretty_print - returns a string with the title and the date concatenated with a colone (:) character seperating them (e.g., The Matrix 4: 2021)
4. Movie#cast - returns an array of actor objects that have a role in the movie
5. Movie#credits - returns a hash where the keys are the character names of the roles in the movies and the values are the corresponding actor full names - e.g.

> batman.credits 
> # { 
> #  "Batman" => "Michael Keaton", 
> #  "Joker" => "Jack Nicholson"
> # }

6. Movie.by_year(year) - accepts an interger year argument and returns an array of movie objects from that year

1. Role - has the following attributes: actor - actor, movie - movie, character_name - string representing the name of the character
   • Role#actor, Role#movie, and Role#character_name methods should all return the respective attributes
   • all attributes can be updated
2. Role.all - returns an array of all the role objects in the collection
3. Role#movie - returns the movie object the role belongs to
4. Role#actor - returns the actor object that played the role
