This is a library of all dendriform data structures, such as red black tree, avl trees, b+ trees and so on.
All of dendriform data structures in the library has no allocater.
So, you must provide memory space by yourself/yourselves to use the dendriform data structures.
The library is written by C++ language, C language users can't use the library.
However, if you want to use the library by C language, you can make C language interfaces by yourself.
If you have some good advice, please send me a issues to tell me.
