This function determines whether to obtain knn information using an exact brute force approach or using an approximate algorithm
knn.info(d, config, brute.force = TRUE)data matrix
list with settings; relevant settings are as follows: input - "data" or "dist" n.neighbors - number of neighbors k metric.function - function with signature f(a, b)
logical, during development, set FALSE to force stochastic knn
list with at least two components, indexes and distances
