Comments:
NB. This does NOT move linearly around the circle. it goes in octants.

int octant;

Current octant.

int radius;

int d;

int deltaE;

int deltaSE;

int x;

int y;

Index2dC offset;

Index2dC data;

CircleIterC(int radius = 1,Index2dC nOffset = Index2dC(0,0))

Constructor.

void First()

Goto first point on circle.

BooleanT IsElm() const

At valid position ?

const Index2dC & Data() const

Get point.
Largest error from radius should be less than 0.5

BooleanT Next()

Goto next point.

void Dummy()
