R-tree star C++ implementation in container-style
MathRTreeStar.h - consists template of container using R*-tree algorithm MathMBR.h - consists template of class declaring MBR (minimal boundary rectangle)
tests directory consists some geometrical tests of inserting/deleting elements in R*-tree. Tests use Qt5 library. RTreeTest/RTreeViewer.cpp:38-43 locates example of find elements in R*-tree.
