comments
clean up and add rtest for double nintegrate
change list of singularities to an opt rather than optional.
add support for it  in defmfun1
added code to store opts during call to a defmfun1 func.
but it is commented out because:
 1)  it is not quite right ('Rule is removed)
 2)  there is not a good use yet
 3)  would have to be able to disable to avoid overhead on
      all funcs.
add multi-dim integral support
find more integrals that work and that do not.
update examples
