Someone from my class requested

   R. J. Spiteri, S. J. Ruuth, A new class of optimal high-order 
preserving time discretization methods, SIAM J. Numer. Anal. 40 (2002) 

which is a fourth order, five stage method that we do not appear to 
have. How hard is this to add?




What most experimenters take for granted before they begin their 
experiments is infinitely more interesting than any results to which 
their experiments lead.
