Only print total summary after all tests run.
Put calculated results from each iteration of a test in a separate
IOR_results_t structure. Clean up the allocation and freeing code
for these caluclated bits, which allowing us to hang onto the results
until the end of all tests. That in turn allows us to perform one
big summary at the end of all of the tests.
Clean up the header files to only contain those things that
need to be shared between .c files.
Functions that are not shared are now declared static to
make their file scope explicit. Functions that ARE shared
are declared in appropriate headers.
I am not going to claim that I caugh everything, but at
least it is a good start.
