I found that in ICG I have access to the canonical type of a variable which
in most cases is the type I should process. Doing this eliminates the
need for some of the code that resolved typedefs because the canonical type
has already done that.

Gave each sim their own model directory, or in some cases just
a header file. Each sim in the test directory is now independent
of each other. Modifying one test will not affect any other test.

Moved SIM_test_ip and a couple of other sims that depend on the same model set
to a new test directory. I'm doing a couple of sims at a time.
