      - If applied:
          This commit allows the user to compute:
            - the Lamb vector (https://en.wikipedia.org/wiki/Lamb_vector),
            - on-the-fly or via postProcess utility
            - for a given volVectorField (one per functionObject entry)
    
      - Why:
          The motivation is the literature-reported quantitative connection
          between the Lamb vector (divergence) and the spatially localised
          instantaneous fluid motions, e.g. high- and low-momentum fluid
          parcels, which possess considerable level of capacity to affect
          the rate of change of momentum, and to generate forces such as drag.
    
      - Verification:
          - Smooth-wall plane channel flow case (Moser et al. 1999) by
              # Curtis et al. (2008) On the Lamb vector divergence
                in Navier–Stokes flows, doi:10.1017/S0022112008002760
    
      - What's next:
          - The verification-show case
          - Extended code guide entry titled "Lamb vector"
