A collection of multi-dimensional data structure and indexing algorithm.

this is a c++ library, and is a collection of various data structures designed to efficiently store and query multi-dimensional data for various filtering criteria. different structures are optimized for different query needs.

this library is a source-code only library. it??s designed to be header-only meaning that the user program does not need to link to any additional shared library in order to use these data structures. the data structures are all available as c++ templates.
