A GfsParticle is a basic inert Lagrangian particle.

The syntax in parameter files is

ID X Y Z

where ID is a unique identifier (an unsigned integer) and (X,Y,Z) the particle position.

Although GfsParticle is derived from GfsEvent, it inherits neither its read nor write methods, so timing (start, end ...) is not specified individually but only for whole GfsEventLists of particles.

Particles with more properties can be created using the GfsParticulate subclass.
