print best time of benchmark (as well as median)
fixed a bug in IterableIntervalProjector2D
put XYRandomAccessibleProjector back in for benchmarks
benchmark: project slices of a 3D img resp real-view into 2D img

results on 2.8 GHz Core i7 Macbook pro, jdk 1.6.0_65:

When each test is run individually, median / best times over 100 runs are

IterableIntervalProjector2D Img
36 / 35 ms
RandomAccessibleProjector2D Img
