full benchmark code for reduced input file

The attached input file contains 1400 example vectors. This benchmark programm
calls cosineSimilarity 700 x 700 times (controlled by slices / foreach loops in
main). Sufficient to reproduce.

The timings in the bug report are based on 1000 x 1000 calls of
cosineSimilarity and 2000 example vectors.

Path to input file is hard coded (same directory) -> line 11
