Class
    Foam::parcelCloudBase

Description
    Virtual abstract base class for parcel clouds. Inserted by ParcelCloudBase
    into the base of the cloud template hierarchy and adds virtualisation of
    most methods defined by the clouds.

    Note that the "evolve" method is not virtualised here. Due to the way in
    which TrackCloudType and trackingData templating work, it is not possible
    to virtualise this method directly. Instead it has to be wrapped. That is
    achieved by the parcelCloud and ParcelCloud classes.
