Random number generator (RNG) is used at several instances of a molecular dynamics simulation
such as the initialization of atomic velocities, Andersen thermostat, etc.
The seed for the RNG can be supplied by the user via the parameter RANDOM_SEED
in the INCAR.
This is useful, for instance, if one needs to reproduce a previously performed calculation.
RANDOM_SEED=[int array] seed for random number generator
Generated randomly on the basis of the system clock
The initial value of RANDOM_SEED, and the value after performing each
MD step are written in the REPORT file.
