    Build a planar MPAS mesh
    Parameters
    ----------
    cellWidth : ndarray
        m x n array of cell width in km
    x, y : ndarray
        arrays defining planar coordinates in meters
    geom_points : ndarray
        list of point coordinates for bounding polygon for the planar mesh
    geom_edges : ndarray
        list of edges between points in ``geom_points`` that define the
        bounding polygon
    out_filename : str, optional
        The file name of the resulting MPAS mesh
    vtk_dir : str, optional
        The name of the directory where mesh data will be extracted for viewing
        in ParaVeiw.
    preserve_floodplain : bool, optional
        Whether a flood plain (bathymetry above z = 0) should  be preserved in
        the mesh
    floodplain_elevation : float, optional
        The elevation in meters to which the flood plain is preserved
    do_inject_bathymetry : bool, optional
        Whether one of the default bathymetry datasets, ``earth_relief_15s.nc``
        or ``topo.msh``, should be added to the MPAS mesh
    logger : logging.Logger, optional
        A logger for the output if not stdout
    use_progress_bar : bool, optional
        Whether to display progress bars (problematic in logging to a file)
