Emergency Room Project

Implement a generic version of the Heap data structure then use it to build an Emergency Room project that uses a heap-based priority queue for patients. I have a more detailed description in the file below and I have also provided the codes that is needed for this project.
This project should have 5 classes called Heap, HeapDemo, PatientComparator, EmergencyRoom, and EmergencyRoomDemo all in java. I have provided a couple of the classes needed below to help you code the rest.
