Plan Structure for GeomStreamer

[tcdude]

Idea:

Shape / Noise / L-System -> Producer -> GeomStreamer

The main function of the GeomStreamer is to serve as bridge between the location aware Panda3D app and the various Producer objects that deliver the needed geometry to Panda3D.
GeomStreamer is agnostic about the type of geometry that is being created and is supposed to be subclassed. It should only provide convenience methods and properties, that apply globally to the GeomStreamer class such as:

• GeomNode caching
• Basic LOD implementation for large Geoms (Terrains / Planets / Environments / etc.)
• LOD implementation for static Geoms (Plants / Objects / etc.)

Others will be identified during implementation and testing
