  __Pyx_DOCSTR("kd-tree for quick nearest-neighbor lookup\n\n    This class provides an index into a set of k-dimensional points\n    which can be used to rapidly look up the nearest neighbors of any\n    point. \n\n    The algorithm used is described in Maneewongvatana and Mount 1999. \n    The general idea is that the kd-tree is a binary trie, each of whose\n    nodes represents an axis-aligned hyperrectangle. Each node specifies\n    an axis and splits the set of points based on whether their coordinate\n    along that axis is greater than or less than a particular value. \n\n    During construction, the axis and splitting point are chosen by the \n    \"sliding midpoint\" rule, which ensures that the cells do not all\n    become long and thin. \n\n    The tree can be queried for the r closest neighbors of any given point \n    (optionally returning only those within some maximum distance of the \n    point). It can also be queried, with a substantial gain in efficiency, \n    for the r approximate closest neighbors.\n\n    For large dimensions (20 is already large) do not expect this to run \n    significantly faster than brute force. High-dimensional nearest-neighbor\n    queries are a substantial open problem in computer science.\n    "), /*tp_doc*/
