Library Header Files

This folder contains all the header needed to use the library
To use it, add the "include" folder to the search path of the compiler
User only needs to know rabit.h and rabit_serializable.h in order to use the library
Folder rabit contains headers for internal engine and template's implementation
Not all .h files in the project are in the "include" folder, .h files that are internally used by the library remain at src
