Bbtree: Fastest Ordered Map

Bbtree is a C++ library that provides an ordered map that is designed to be the fastest ordered map. It is implemented on top of a B-tree data structure. The library is open-source and can be used as a drop-in replacement for std::map in C++ programs. Bbtree has been shown to be faster than std::map in various benchmarks, with a speedup of up to 10x. The library is designed to be thread-safe and has a simple and efficient API. It is also designed to work with both small and large datasets.
