Class
    Foam::injectedParticle
 
Description
    Primarily stores particle properties so that it can be injected at a later
    time.  Note that this stores its own local position as opposed to the
    base particle class barycentric coordinates since the particle is not
    (usually) attached to a mesh, and instead used for post-processing.
