Detailed Description

A Curve is made of 2 nodes (start and end points) and a set of controlPoints.

It may be used to represent Areas, but can also be used independently. This is the 'Lazy' version of Curves. Allows real-time loading for LazyGraphs. Can be deleted and reloaded at any time depending on the needs.
