Extension of normal_t class
White space stuff
Removed redundant operations and checks
New normal smoothing algorithm that fits better on highly subdivided meshes
So no more reflect/transmit distorsion
Redundant dereferencing removed
Removed redundant extra function
Operation moved to triangle intersection
Calculation of barycentyric coordinate w (b0 in our case) moved here
Fixed transparency iossue on debug integrator
Refactoring of material library names
Algorithm for autosmoothing normals with angle threshold below 180 degrees fixed
Returned checks for invalid vertex normal indices
Final fix for the normal smoothing algorithm
