Hi!

I just discovered this nice functionality in boost, but while trying something 
as simple as calculating a mean from a set of numbers, I hit a strange 
drawback:

It seems to be impossible to use the same accumulator again for a different 
set of numbers, because I cannot clear/ reset it. I found some old (ok, March 
2009)  discussions about this, but nothing in the documentation.

By the way, does the accumulator do something to prevent an overflow when I 
add up everything into one variable? And does it prevent a loss of precision, 
when at a late stage the variable I sum everything into is very big, but the 
thing I add is very small? 
Maybe it would be a good idea to mention this in the documentation, as well...

Many thanks in advance for any help

Tim
