Moreover, +now the numbering of the ids is correct also if we call the method more than +one time. Newly added particles, if ids are not specified, now correctly get +the first available ids. +Added a new version of Particles::ParticleHandler::add_global_particles() that +takes a vector of Particles::Particle objects instead of just their positions. +This can be used in conjunction with the signal +Particles::ParticleHandler::Signals::particle_lost() to reinsert +Particles::Particle objects that went out of the locally owned and ghost cells. +
