Gravitational Dynamics Nbody integrator

The astrophysics "Nbody problem" consist in a dynamical N celestial bodies model which interact gravitationally.
Solving this problem implies understand and predict the movement of the system components, for example, the Solar System, a stars cumulus, or a galaxy.
To systems with more than 3 bodies, which are most of the interesting astronomical systems, the problem do not have an analytic solution, and it is necessary to use computational methods, which are progresively more expensives to largest values of N.
GraviDy is a new GPU, directsummation Nbody integrator written from scratch and based on the Hermite scheme. The most important features of the code are:
