// Returns unit length normalized version of vector v.

// v = The vector to normalize.
// Examples:
// normalize([10,0,0]); // Returns: [1,0,0]
// normalize([0,10,0]); // Returns: [0,1,0]
// normalize([0,0,10]); // Returns: [0,0,1]
// normalize([0,-10,0]); // Returns: [0,-1,0]
// normalize([0,0,0]); // Returns: [0,0,0]
