• Added support for BufferGeometry.groups in subdivision and edge split functions

• Added morph attributes to algorithm, allowing for morph target animation
• Implemented params object for modify() function to handle growing list of parameters
• Added preserveEdge parameter to keep geometry edges from being smoothed. This is most noticeable in 2D geometries, or geometries with non-cohesive polyhedron, such as TeapotGeometry
