Added result coercion helpers plus exact recall summaries and
candidate reranking utilities.
bigKNN 0.2.0
Added prepared exact references with
knn_prepare_bigmatrix(),
knn_search_prepared(), and
knn_search_stream_prepared() for repeated search
workloads.
Added exact radius-search APIs with in-memory and streamed outputs,
including count_within_radius_bigmatrix(),
radius_bigmatrix(), and
radius_stream_bigmatrix().
Expanded metric support from Euclidean distance to
"sqeuclidean" and "cosine".
Added exact graph builders for directed kNN, mutual kNN, and
shared-nearest-neighbour graphs.
bigKNN 0.1.0
Initial release with exact Euclidean
k-nearest-neighbour search on
bigmemory::big.matrix references.
Added self-search and external-query search against
big.matrix and dense matrix inputs.
Added both in-memory and streamed neighbour outputs through
knn_bigmatrix() and
knn_stream_bigmatrix().
Established package documentation, compiled backend registration,
and the first regression tests.
