Class
    Foam::interpolations::cellPointFace
 
Description
    Piecewise-linear interpolation method. Uses volPointInterpolation to create
    values on the points and linear surfaceInterpolation to create values at
    the face-centres. Then uses a face-centre tetrahedral decomposition to
    linearly interpolate between the values at the points, at the face-centres
    and at the cell-centres.
