Detailed Description

Functor class for moving particles.

This class captures references to particle positions and velocities and overloads the call operator to allow use in STL algorithms in particular the std::for_each method

call operator applying motion to the n-th particle.

overload of the call operator to apply motion to the n-th particle use velocity field for deterministic motion component plus gaussian noise to represent diffusion/Brownian motion
