This class defines a information node in the scene graph. This node has no effect during traversal. It is used to store information in the scene graph, typically for application-specific purposes, copyright messages, or other strings. This node differs from the SoLabel node in that it stores its information in an SbString instead of an SbName; the SbString is more efficient for storing long strings that don't have to be accessed very often. Use an SoLabel node for short strings that have to be accessed more often.
