develop the structure of the project. In folder include there is the C++ code. In external folder we will include the neccessary libraries. In folder test we run tests when we make changes to the algorithm. In folder R-proj/src there is a Rcpp interface. We develop the random_point_on_dSphere class by moving the template argument to the function sample_point.
