This small optimization allows us to improve from:
OLD php: 0.012100038051605 Sec.
New native: 0.0096198790073395 Sec.
(This is already 20 percent faster)
..to:
OLD php: 0.012276937961578 Sec.
New native: 0.0022540950775146 Sec.
What is 80 percent faster than our PHP class.
It not use the 'length' native versions of dlib, due I have to convert the
array to the vector, which will take the same time, and then I will use the
native method.
