Add support to allow a LineProfileCharacteristicItem to be identified as lying on a plane or a curved surface.

[GitHubDaveSmith]

We would like to be able to identify a line as lying on a nominally flat surface such as a plane or a curved surface such as that of a cylinder.

This request needs clarification. Is a boolean sufficient, or is the id of a feature needed, or is the id of an item of geometry needed?

Do you mean: some type of a reference to the "parent" 3D feature on which the given 2D feature lies?

Yes, exactly. Some types of supplemental geometry (e.g. a curve on a surface that is toleranced as a profile of line) must be associated with one or more BRep surface(s) for it to be measurable.

Currently we are using a custom attribute of type 'AttributeBool' and so for us a simple boolean would be sufficient for our needs. However, if an optional reference to the "parent" 3D was provided then I am sure that this would work equally well since the presence of a reference would be equivalent to a boolean value of 'true', and no reference would be equivalent to 'false'.
