"num_images()" invocations of "sync all"?

[bcfriesen]

In commit c86ac77 ("now prints precipitation mid way through the domain after the run completes"), a loop was added to the end of test-ideal.f90 which invokes sync all num_images() times. This becomes expensive at large numbers of images. What was the intent of this?

sync all

This was added to keep all of print statements in order to make it easier for a human to parse the output. This entire section can be removed, it was simply added so I could confirm the algorithm was producing reasonable results (and not just complete garbage).
