New description:

 Two commonly desired constructions in a Coxeter group are to:
 a) Iterate over all elements of a given length - this happens especially
 in affine or other infinite coxeter groups in order to test hypotheses,
 construct homogenous elements, etc...
 b) Choose a random element, possibly with length specified.  This often
 occurs to see if a non-special element has a given property.

 Iterating over all elements of a given length in particular has a nice
 solution (due to N. Thiery) and anecdotally has been implemented (usually
 in an inelegant fashion) by numerous community members in response to
 short-term problems.

 We provide some code implementing these functions!
