This class provides access to set of Polylines. This is a geometry group that is drawn with the same set of rendering at the same time.
Rendering attributes can be set directly to this geometry using the inherited TSLEntityBase::setRendering method. This is called 'Entity Rendering'.
Rendering can be applied to a large range of geometry using 'Feature Rendering' which is set by the datalayer using TSLDataLayer::addFeatureRendering which creates a featureID. The featureID can then have attributes applied to it using TSLDataLayer::setFeatureRendering.
A featureID can be applied to geometry on creation, or it can be added later using TSLEntityBase::featureID.
Valid Rendering Attributes for TSLMultiPolyline:
The above is not a complete list, see TSLRenderingAttributeInt, TSLRenderingAttributeDouble and TSLRenderingAttributeBool for more details.

Add a coordinate to the TSLMultiPolyline.
| part | the coordset representing the TSLPolyline to add |
| pos | the position at which to add the polyline. By default the polyline will be added after the current last polyline. If the position entered is greater than the existing number of parts the polyline is also added after the current last polyline. |

Add a coordinate to the TSLMultiPolyline.
| part | the TSLPolyline to add. |
| pos | the position at which to add the polyline. By default the polyline will be added after the current last polyline. If the position entered is greater than the existing number of parts the polyline is also added after the current last polyline. |
