org.apache.lucene.spatial.prefix.tree.SpatialPrefixTree
A spatial Prefix Tree, or Trie, which decomposes shapes into prefixed strings at variable lengths corresponding to variable precision. Each string corresponds to a rectangular spatial region. This approach is also referred to "Grids", "Tiles", and "Spatial Tiers".
Implementations of this class should be thread-safe and immutable once initialized. @lucene.experimental
