Detailed Description

template<typename T, typename S>
class olb::PolarToCartesian2D< T, S >

This class converts polar coordinates of point x (x[0] = radius, x[1] = phi) to Cartesian coordinates (wrote into output field).

Initial situation for the Cartesian coordinate system is that angle phi lies in the x-y-plane and turns util::round the _polarOrigin in math. pos sense.
