/* An object of class Vector is deemed to be a vector on the
two dimensional plane from the origin to the point (x,y).
Methods (built-in functions) associated with a Vector object
sets it to a value, returns the present value, scales it,
rotates it or reflects it about either the x or y axis (or
both). There are also methods to add or subtract another
vector to it. However these operations can only be carried
out when both operands are vectors.
Your task is to provide the actual code for the methods
associated with vector. As always, these should be in a file
called "assign6.cpp" which should begin with the line
#include "assign6.h"

  HINTS: 
	1. math functions may be used by including <math.h>
	2. the code for this class is VERY simple.
