1. A Nurse data class (a subclass of Person) to contain these:
   1. floor
   2. shift (this will be in the data file as "day" and "evening")
   3. highest degree earned (this will be an LPN, RN or a BSN)
2. Add the Nurse objects to the ArrayList (the NursingStaff data file is here: NursingStaff    Download NursingStaff   (NOTE THE FILE NAME HERE)
3. All ID's assigned to Nurse objects MUST contain an "N-" in front of the ID.  Check the ID number of all Nurse objects - add an "N-" to the front of any ID that is missing this (you may need to shop around the Java API in the String package)
   1. For example, the first nurse is Yong Ferrell.  In the data file the ID for Yong is C2Y8N2, it needs to be N-C2Y8N2.
4. The calculateTotal() method for a Nurse object will calculate (TBD) - this will be added soon, since you need a method for calculateTotal() to get a clean compile, you may at this time an empty method (a stub) that has no functionality
5. the following given the addition of the Nurse objects
   1. Every floor must have at least one Nurse assigned to it per shift - confirm this is true for your hospital.
   2. There is to be one Nurse assigned to every 3 patients on a floor - confirm this is true for your hospital.
      1. Determine if a floor is understaffed or overstaffed based on this fact
6. By menu option (I would recommend a sub menu for querying the Nurse objects, but this is not required)
   1. Display all day nurses by floor
      1. Your code will display the floor and the nurses on the day shift on that floor
   2. Display all night nurses by floor (see 1.1 above)
      1. Display whether a floor is understaffed or overstaffed per shift given the rule in 4.2 above.
      2. Name ID number shift floor highest degree earned
