Added float, uint64, and uchar params to Algorithm
Made changes to work in cv::Algorithm with parameters of these types.
Also fixed SimpleBlobDetector -- now it can be created by
cv::Algorithm::create and it can work with cv::Algorithm::set/get.
Try to fix Mac compilation issue.
The next attempt to fix a build error on Mac.
Removed urequired functions
Changed error message in Algorithm::get.
Made changes to avoid warnings (Windows compilation).
