Analytic Curve: A curve given by analytic expressions.

An AnalyticCurve is a 2D drawing element that draws the graph of a curve (that is, a set of points (x(t),y(t))) from the analytic expressions (based on the free variable t) provided to compute these points.

The curve can be moved by dragging any of its points, invoking up to five different actions.

A one-parameter family of curves is also possible, using the Parametric Family properties.
