Class
    Foam::InjectedParticleInjection

Description
    Replays an set of particle data based on an injectedParticleCloud, using
    the assumption of one particle per parcel.

Usage
    \verbatim
    model1
    {
        type            injectedParticleInjection;
        SOI             0;
        massTotal       0; // Place holder only
        parcelBasisType fixed;
        nParticle       1; // 1 particle per parcel
        cloud           eulerianParticleCloud;
        positionOffset  (-0.025 2 -0.025);
    }
    \endverbatim
