Class
    Foam::arraySet

Description
    Specifies an x,y,z array of uniformly distributed sampling points.

    For a dictionary specification:
    \table
        Property | Description                             | Required | Default
        type     | array                                   | yes      |
        axis     | x, y, z, xyz, distance                  | yes      |
        pointsDensity | The sampling density as (x y z) integers | yes      |
        spanBox   | The sample box dimensions (vector)     | yes      |
    \endtable

    The dictionary should also contain an embedded (Cartesian) coordinateSystem
    specification, for example,

    \verbatim
        origin (-0.05 -0.05 -0.05);
        rotation
        {
            type    axes;
            e1 (1 0 0);
            e2 (0 1 0);
        }
    \endverbatim
