Consider a Hospital with a fixed number of rooms for patients. The application needs to keep track

of patients, their emergency contact person, and rooms. Patients need to be admitted when brought

to the clinic for care and discharged afterwards. Each room can be empty, or there can be a patient

assigned to it$.$ New patients can only be admitted if there is an available room, and can only be

assigned to an empty room. Each patient can have zero or more doctors $($when first admitted, there

may not be a doctor assigned to them$)$; we need to be able to assign doctors to admitted patients, be

able to find out which doctors have been assigned to each patient, and lookup the emergency contact

for a specific patient. Each doctor can have zero or more patients assigned, we need a way to assign

doctors to patients, and find out which patients are assigned to each doctor. Doctors will start their

shift, care for some number of admitted patients while on duty, and end their shift after some number

of hours.
