Interpolates supplied nodes with bezier line segments.
<p>
The line interpolator interpolates supplied nodes (see InterpolateLine) with bezier line segments. The finess of the curve may be controlled using SetMaximumCurveError and SetMaximumNumberOfLineSegments.<p>

<p>
Span of the interpolator. ie. the number of control points its supposed to interpolate given a node. The first argument is the current nodeIndex. ie, you'd be trying to interpolate between nodes "nodeIndex" and "nodeIndex-1", unless you're closing the contour in which case, you're trying to interpolate "nodeIndex" and "Node=0". The node span is returned in a <a class="el" href="a00900.html" title="dynamic, self-adjusting array of int">vtkIntArray</a>. The node span is returned in a <a class="el" href="a00900.html" title="dynamic, self-adjusting array of int">vtkIntArray</a>. The node span returned by this interpolator will be a 2-tuple with a span of 4.
