This class describes a MultiCurve approximating a Multiline. As a Multiline is a set of n lines, a MultiCurve is a set of n curves. These curves are Bezier curves. A MultiCurve is composed of m MultiPoint. The approximating degree of these n curves is the same for each one.
Example of a MultiCurve composed of MultiPoints:
