  -----------
  adding more realistic test of sum over Feynman diagrams

Note: On my machine (i7 4 cores, g++ 4.9) the realistic test passes.
I checked the assembly code and it seems the compiler has not unrolled
the explicit for loop in test_SUM_benchmark_small_sum.  However, it
has unrolled the call to SUM() in test_SUM_benchmark_small_sum.

This means, that the could consider using the SUM() macro for small
(even nested) loops (N <= 10).
