Problem set 3.  
Put all of projects within your own namespace.


1. (30) Create a class for complex numbers.  Include functions to
   return the real and imaginary parts separately, create the
   conjugate of a complex value, the absolute value, the norm, and the
   phase angle of the complex value in polar coordinates.  Overload
   the following operators: +, -, *, /,  +=, -=, *=, /=, >>, <<, ==.
   Include a copy constructor, and a destructor.  Use double as the
   base type for the values.

2. (25) Chapter 11, Programming Project 2.

3. (20) Chapter 11, Programming Project 5 -- Similar to previously, but
   overload the operators.
