/*!
* The Curve class is used by LineString as parent class.
* This class could not be used directly.
*
* From the OGC Candidate Implementation Specification:
* "A Curve is a 1-dimensional geometric object usually stored as a sequence of Points, with the subtype of Curve
* specifying the form of the interpolation between Points. This specification defines only one subclass of Curve,
* LineString, which uses a linear interpolation between Points."
