nanoflann 1.5.0: Released Jun 16, 2023

• API changes:
  • Users of radius search should change their result placeholder type:
    std::vector<std::pair<IndexType, DistanceType>> => std::vector<nanoflann::ResultItem<IndexType, DistanceType>>. (See #166 for the motivation of this change).
  • More concise auxiliary (internal) type name:
    array_or_vector_selector -> array_or_vector.
  • Remove obsolete parameter nChecks_IGNORED. Removed from SearchParams
    constructor too, so that structure has been renamed SearchParameters to
    enforce users to update the code and avoid mistakes with the order of its
    ctor parameters.
  • Added method RadiusResultSet::empty()
  • Template argument rename: AccesorType => IndexType (does not actually affect user code at all).
  • Added concurrent tree building support, refer to KDTreeSingleIndexAdaptorParams::n_thread_build.
• Other changes:
  • Macros to avoid conflicts with X11 symbols.
  • Inline an auxiliary example function in case users want to use it and
    include the file in multiple translation units (Closes #182).
  • Move all benchmarking code, data, and scripts to its own repository to keep this repo as clean as possible.
  • Fix "potentially uninitialized" GCC warning.
  • Clarified, even more, in docs and examples, that L2 distances are squared distances.
  • Removed the (with modern compilers) now useless inline keyword in class members.
  • Add examples with GUI (requires mrpt-gui):
    • nanoflann_gui_example_R3: Radius search on R³ Euclidean space.
    • nanoflann_gui_example_bearings: NN search on non-Euclidean spaces.
• BUGFIXES:
  • Avoid segfault if saving an empty index (Closes #205).
