Class
    Foam::surfaceWriters::ensightWriter

Description
    A surfaceWriter for Ensight format.

    \verbatim
    formatOptions
    {
        ensight
        {
            format          ascii;
            collateTimes    true;
        }
    }
    \endverbatim

    Format options for ensight:
    \table
        Property | Description                              | Required | Default
        format   | ascii/binary                             | no  | ascii
        collateTimes | Use common geometry for times        | no  | true
        scale       | Output geometry scaling               | no  | 1
        transform   | Output coordinate transform           | no  |
        fieldLevel  | Subtract field level before scaling   | no  | empty dict
        fieldScale  | Output field scaling                  | no  | empty dict
    \endtable

    The collated format maintains an internal list of the known times
    as well as a file-cached version with the field information.
    The information is used for restarts.
