Lifeboat Survival

Tragedy strikes a major cruise line as their flagship collides with an
iceberg in the Caribbean Sea.  However, due to an ever-so-slight flaw in
the engineering of the lifeboats, each lifeboat can carry only ONE person!
You are called upon to write a computer program to help the people in each
lifeboat determine who gets to remain in the lifeboat while the others
jump and try to swim to shore.

Write a program that does an eeny-meeny-miny-moe around all the people in
the lifeboat - the nth person must jump off of the lifeboat.  This
process is repeated again - again the nth person jumps out.  The program
takes two integers as input from the user, one for the number of people in
the lifeboat, and the other to represent the number n.  Also, the
user can specify whether the eeny-meeny-miny-moe should go in the forward
direction or reverse direction. 

For example, say there are 7 people in the boat and every 4th person has
to jump, and we count in the forward direction.  Start counting with
Person 1.  Person 1 = 1, Person 2 = 2, Person 3 = 3, Person 4 = 4 so Person 4
jumps out.

Go again, start counting where the last iteration left off, when you've
reached the last person, revisit Person 1.
Person 5 = 1, Person 6 = 2, Person 7 = 3, Person 1 = 4 so Person 1 jumps 
out.

Go again, start counting where the last iteration left off, skip over
people that have already jumped.
Person 2 = 1, Person 3 = 2, Person 5 = 3, Person 6 = 4 so Person 6 has to
jump.

Continue until there is only one person left in the lifeboat.

Project requirements:
The program shall solicit two integers from the user.  One integer
represents the number of people in the lifeboat.  The other represents the
value n for which every nth person has to jump.
The program shall allow the user to to choose to iterate forward or
backward through the lifeboat passengers.
You must implement this project using a doubly-linked circular
buffer class to store the list of people left in the boat.
The program shall be all original code (specifically a doubly-linked
circular buffer class, not a STL vector or equivalent).
Dynamic memory shall be used (i.e. each "Person" shall be allocated on
dynamically, and deleted when they jump out of the lifeboat).

To turn in:
The class/classes that model this project.
The main program that determines who stays in the lifeboat, and output
demonstrating the correct functionality of your program.
A test driver with output that shows you adequately tested your classe(s).
The test driver must include testing for the copy constructor, operator=
and the destructor.
Submit the project according to the usual procedure.
