Program 3
// A very simple class point with public data representation.
// An incomplete sketch.
// This version uses polar representation.
// NOT RECOMMENDED because of public data representation.

It becomes a big challenge to use this version of class
Point together with client shown previously.
A point represented by polar coordinates.
Still public. Still not recommended. 
A point is constructed in terms of 
rectangular coordinates. The transformation
is not shown here.
It is easy to program the Rotate method.
Rotation and polar coordinates fits well.
