* renamed ChangeColor to UICircleChangeColor for clarity
* renamed ChangeDensity to UICircleChangeDensity for clarity
* removed unnecessary usings
* updates scene to match UI control start positions
* Added progress indicator capability to the component.
* Component uses AddUIVertexStream to generate vertices and indices of triangle order.
* Improves base geometry generation to prevent edge sliding on segment value changes (tris density, now called Arc Steps).
* Corrects a minor issue with base mesh where first vertex is generate at center (only visable in wireframe mode at certain angles).
