Detailed Description

ShaderFactory attaches a shader to a node.

Build pathnames to files container GLSL shader source code. Naming convention: ${shaderName}_vert.glsl ${shaderName}_frag.glsl

Design notes: Abstracts OSG to a degree, but assumes a scene-graph capable of attaching a shader program to any kind of node.
