    ENH: Lagrangian - provided backwards compatibility for cases using the · 984f8f00

    old "positions" file form
    The change to barycentric-based tracking changed the contents of the
    cloud "positions" file to a new format comprising the barycentric
    co-ordinates and other cell position-based info.  This broke
    backwards compatibility, providing no option to restart old cases
    (v1706 and earlier), and caused difficulties for dependent code, e.g.
    for post-processing utilities that could only infer the contents only
    after reading.
    The barycentric position info is now written to a file called
    "coordinates" with provision to restart old cases for which only the
    "positions" file is available. Related utilities, e.g. for parallel
    running and data conversion have been updated to be able to support both
    file types.
    To write the "positions" file by default, use set the following option
    in the InfoSwitches section of the controlDict:
        writeLagrangianPositions 1;
