The comment of the detect method is difficult to understand

Below is the comment of the detect method.

attributes: [Optional] Analyze and return the one or more specified
face attributes in the comma-separated string like
"returnFaceAttributes=age,gender". Supported face attributes
include age, gender, headPose, smile, facialHair, glasses and
emotion. Note that each face attribute analysis has additional
computational and time cost.

quote from face.py

The attributes arg should be "age,gender", not "returnFaceAttributes=age,gender".

Thanks for your suggestion. That's my fault, I was so lazy that I just blindly copied the API reference description at that time. I will consider to fix it on next release. Any pull requests are also welcome!
