Class
    Foam::sampledSets::points

Description
    Specified point samples. Optionally ordered into a continuous path.
    Ordering is an optimisation; it enables tracking from one point to the
    next. If ordering is off, each point is searched for individually.

Usage
    \table
        Property    | Description                            | Req'd? | Default
        points      | The points to sample                   | yes    |
        ordered     | Are the points in order?               | yes    |
        axis        | The coordinate axis that is written    | yes    |
    \endtable
