Class
    Foam::searchablePlate
 
Description
    Searching on finite plate. Plate has to be aligned with coordinate
    axes.
    Plate defined as origin and span. One of the components of span has
    to be 0 which defines the normal direction. E.g.
 
    \verbatim
    span    = (Sx Sy 0)     // plate in x-y plane
    origin  = (Ox Oy Oz)
    \endverbatim
 
    now plane is from (Ox Oy Oz) to (Ox+Sx Oy+Sy Oz)

        Property    | Description                       | Required | Default
        type        | plate                             | selector |
        origin      | The minimum corner of the plate   | yes |
        span        | The plate dimensions              | yes |
    \endtable
