Class
    Foam::ensightOutputSurface

Description
    A variant of ensightFaces that holds references to contiguous
    points/faces with its own encapsulated write methods.
    The surface is assumed to have been merged prior, thus the output is
    serial-only.

Note
    The primary use is for the Foam::surfaceWriters::ensightWriter
    but can be used independently as well.
