18.2.10 Class `MultiCurve'
--------------------------
A `MultiCurve' is a geometry collection composed of `Curve' elements.
`MultiCurve' is a non-instantiable class.
`MultiCurve' Properties
.......................
* A `MultiCurve' is a one-dimensional geometry.
* A `MultiCurve' is simple if and only if all of its elements are
simple; the only intersections between any two elements occur at
points that are on the boundaries of both elements.
* A `MultiCurve' boundary is obtained by applying the "mod 2 union
rule" (also known as the "odd-even rule"): A point is in the
boundary of a `MultiCurve' if it is in the boundaries of an odd
number of `MultiCurve' elements.
* A `MultiCurve' is closed if all of its elements are closed.
* The boundary of a closed `MultiCurve' is always empty.
