Class
    Foam::coordSetWriters::abaqusWriter

Description
    Write coordSet(s) as Abaqus point fields

    Example usage
    \verbatim
    T
    {
        type        sets;
        setFormat   abaqus;
        fields      (T);
        sets
        {
            ...

    }
    \endverbatim

    Optional format options

    {
        abaqus

            format          ascii;
