Some Libraries in Face Recognition Examples are missing

[rcmalli]

I have added org.bytedeco.javacv to my gradle project .When I was trying face recognition examples, I noticed that some functions are missing. There is the list of missing libraries

import static org.bytedeco.javacpp.opencv_legacy.;
import static org.bytedeco.javacpp.opencv_face.;

EDIT: After I looked into Javacpp-presets repo I have noticed that bins that are uploaded maven repo not the ones that should be created by the cppbuild.sh files that are shared , because opencv_contrib package is not included in bins but is included in script.

opencv_legacy is no longer part of OpenCV 3.0, so unless we find a replacement for the missing functions, we might as well consider removing that sample entirely. OpenCVFaceRecognizer.java works better anyway. What's your opinion?

opencv_contrib was added after the last release, so it's not part of the current release, that's all.

OpenCVFaceRecognizer.java sample also needs opencv_face package that cannot be found in 1.0 release gradle import.
