+/** 
+    Vertex Attributes are passed all the way though on objects to shaders.
+    
+    If you have your own custom shader, you often need a way to feed it data.  The toolkit will set up the standard data, like vertices, texture coordinates and normals, but sometimes you need something custom.
+    
+    Vertex attributes are the mechanism you use to pass that custom data all the way down to the shader.
+    
+    How the vertex attributes are used depends on the data type, so consult the appropriate object.
