Brute-Force k-nearest neighbor search.
Parameters : x : array of shape [N,D]
representing N points in D dimensions
pt : array-like, last dimension D
An array of points to query
k : a positive integer, giving the number of nearest
neighbors to query
Returns : nbrs : array of integers - shape: pt.shape[:-1] + (k,)
each entry gives the list of indices of neighbors of the corresponding point
