homework_4

What was submitted for hw#4.
Obvious to fix:
- population of Actor’s list of Movies
- Really finding duplicates instead of the way the assignment asked, it
didn’t catch that many.
- Combining data from all duplicates before removing, no data loss, no
duplicate movies / actors, no duplicate data within each movie
- Read right into vector<Movie*> instead of vector<Movie> and then
populating vector<Movie*>
