Message:

Removed atom_trajectoryparticle*, replaced by AtomInfo class now having std::vector<> for trajectories.

AtomInfo:

• AtomInfo stores position, velocity, and force in vectors.
• getter and setter implemented for velocity and force.
• all functions from TrajectoryParticle put into AtomInfo.
• Direct access to velocity and force exchanged by getter/setter everywhere.
• FIX: molecule::LinearInterpolationBetweenConfiguration() extends trajectory to MaxSteps+1 (for endstep).

Other changes:

• gsl_rng_gaussian() exchanged by boost::random specific type.

File:

• src/Thermostats/Langevin.hpp (modified) (2 diffs)
