Golden ratio.

The golden ratio, $\phi$ is equal to $\frac{1+\sqrt{5}}{2} = 1.6180339887498948482\ldots$. We also define $R=\phi-1$ and $C = 1 - R$.

Detailed Description

this static class contains several useful constant values.

This classe uses function in order to avoid the infamous "static initialization order fiasco". C++0x solves this...
