Chris@82: 
Chris@82:    1) bench.c is supposed to test the API---we do not want to #include

Chris@82:    2) this code is a royal mess.  The messiness is due to
Chris@82:       A) confusion between internal fftw tensors and bench_tensor's
Chris@82:          (which we want to keep separate because the benchmark
Chris@82: 	  program tests other routines too)
Chris@82:       B) despite A), our desire to recycle the libbench verifier.
