    Updates an old mosaic cube with a tracking band by removing the tracking band and table and

    placing them into a separate tracking cube. A reference to the tracking cube is added to the

    mosaic label. We also have to update the tracking cube's pixels by subtracting the offsett

    ProcessMosaic adds to each pixel and adding the new offset, the minimum value of an unsigned

    integer. ProcessMosaic also sets pixels that are not from any cube to a default value. If a

    pixel has this value, we set it to Null.

    Updates a mosaic cube with a tracking band created on or before isis version 3.5.2 to be up to 

    date with isis version 3.5.3 or above. Removes the tracking band and table from the input mosaic 

    cube and places them into a separate tracking cube. A reference to the tracking cube is added to 

    the mosaic label. The mosaic cube's bit type remains the same, but the tracking cube's bit type 

    is made unsigned integer. We also have to update the tracking cube's pixels by subtracting the

          Output mosaic and tracking cube

        </brief>

        <description>

          There will be two output cubes: the mosaic cube and the tracking cube, both named

          by the user, but the tracking cube will have "_tracking" appended onto the name.

          The output mosaic cube name that will be up to date with isis version 3.5.3 or above. 

          This cube will not have the tracking band, but instead the tracking information will be 

          placed into a new cube with the same name but with "_tracking" added to the end.
