Hi Gang,
Many thanks for the quick turnaround on this.
This solves the problem that J.S. reported where a Modal Model that
has just a straight through connection was not working. Professor Lee
pointed out that the problem is that a composite actor that has
a SDF Director, a straight through connection and no actors exhibited
the same problem.

I checked in some code to support direct input and out connection. It works
as follows: after the balance equation is solved, if any external port stil
l has zero rate, then 1) if it is a dangling port (i.e., without any interna
l connection), still keep zero rate, 2) if the zero rate is due to the rate
propagation from an inside actor (i.e., connected to zero-rate port of the
inside actor), still keep zero rate 3) otherwise, set the rate to be 1.
I also fixed another problem in the SDFScheduler. It is the reason tunnelin
g2.xml under \sdf\kernel\test\auto\knownFailedTests fails. In the original
scheduler, to avoid infinite recursion of method calls, it is not propagatin
g rate information between directly connected external input and output port
s. I fixed that, I think. So I moved tunneling2.xml back into the normal te
st directory.
BTW, some multiport connection in tunneling2.xml is not rendering properly
on my machine. Specifically, the two links to "typed composite actor0.port"
overlap. Is it beause they are connected to the same relation, since other m
ultiport connection are rendering correctly.
