manuelk dabaac8187 Adding a TBB SmoothNormal Context & Controller
Also:
    - Add a _numVertices member to cpuSmoothNormalContext (for memory reset function)
    - Fix memory reset function in cpuSmoothNormalContext (was performing redundant memsets)
    - Add a resetMemory boolean to cpuSmoothNormalContext to make reset step optional (default is off)
