Add an optional parameter to the "average_precision" function called "sample_neg" that enables random sampling of the negative pairs prior to pairwise cosine distance calculation.
If "sample_neg" is between 0 and 1, sampling is done by percentage (ie. sample_neg = 0.2, then 20% of neg_pairs are sampled).
If "sample_neg" is greater than 1, sampling is done by size (ie. sample_neg = 10 000, then 10 000 neg_pairs are sampled).
The default value for "sample_neg" is 1 - in this case, no sampling is performed.
