//Movie_Vertex.cpp
//Implementation of Movie_Vertex class
//Intention is to provide an infrastructure for storing data about movies in a "node" referred to as a vertex
//The vertex can be connected to other verticies using edges, thus creating a graph
//The Graph class is required as a handler for the movie vertex objects
//A single graph object is made and multiple verticies/edges are added to it
