Hi all,
	I've been using the SampleHistogram class.  My first difficulty was I 
could not find the header files.  After using grep I found that they
were called SmpHist.h and SmpStat.h not _data.h and I got it to compile
and link.  Bit inconsistent there however I got over that.  I could not
find a ref to the header in info.

	I had another slight glitch with x=h.mean; should be x=h.mean();

	My current hick is:-
SampleHistogram h(lo, hi, width); //lo, hi and width declared double.

Int n =h.buckets(); //returns 3 regardless of width.
Int n =h.buckets(); //returns 12 when width is left as default.

	I can work with 12 buckets but thought I'd mention it.  I expected
h.buckets to return width.  Also I do not see why width should be double
I'd have though int would be more appropriate.  I must be missing a
fundamental point somewhere.  Maybe someone could put me straight.  The
rest seems to work like I expected.

		Regards Ian.
