Class
    Foam::boundaryDataSurfaceReader
 
Description
    A boundaryData format surface reader.
    However, the "surface" represented by boundaryData is actually only
    point data!
 
    // Points
    <case>/constant/region0/"boundaryData"/patchName/points
 
    // Values
    <case>/constant/region0/"boundaryData"/patchName/TIME/field
 
    \verbatim
    readOptions
    {
        boundaryData
        {
            points      points;
        }
    }
    \endverbatim
 
    Format options for boundaryData:
    \table
        Property | Description                              | Required | Default
        points   | Name of the "points" file                | no  | points
    \endtable
