Summary: Outlier detection library/package

Special thanks to Dr. Stephane Heritier (Univ Sydney) who recommended "robust 
methods" and more.
Also to Eric Zivot and Bert Gunter (Merck) who suggested the same methods.

I'd better gear up for "modern methods" then.  But I feel it is difficult to 
grasp the concepts of robust methods without knowing the concepts of outlier 
identification and extreme data points.  A classroom issue?
