//
//  CUWireNode.h
//  Cornell Extensions to Cocos2D
//
//  This module provides a scene graph node for wireframes.  Wireframes are lines, not
//  solid shapes.  They have no thickness.  They are primarily useful for debugging.
//
//  This class infinitely better than the horrible DrawNode, which is outside the Cocos2d
//  render pipeline, and hence incredibly slow.  You should avoid that class whenever
//  possible.
