* Component: Virtual_mcnp_output

* Written by: <a href="mailto hennanec@ensimag.fr">Chama Hennane</a> and E. Farhi

*
* Detector-like component that writes neutron state parameters into a
* 'virtual source' neutron file with MCNP/PTRAC format.
*
* %D
* Detector-like component writing neutron state parameters to a
* virtual source neutron file with MCNP/PTRAC format.
* The component geometry is the full plane, and saves the neutron state as
* it exits from the previous component.
* Format is the one used by MCNP 5 files :
*
* position_X position_Y position_Z dir_X dir_Y dir_Z energy weight time
*
* energy is in Mega eV
* positions are in cm and the direction vector is normalized to 1.
*
* %BUGS
* This component will NOT work with parallel execution (MPI).
*
* EXAMPLE:
* To create a file collecting all neutron states with MCNP5 format
* COMPONENT fichier_sortie = Virtual_mcnp_output(
* filename = "exit_guide_result.dat")
* at the position where will be the Virtual_mcnp_input.
*
* %P
* INPUT PARAMETERS
* filename: [str] name of the MCNP5 neutron output file,
* or stdout if left to 0.
