A C++ version of this notebook with some extra notations and implementations

I have personally wrote C++ code representations for all the functions and notations referred in the current readme file and also have implemented some extra features, such as 2D point, 2D line class, 3D point, 3D vector class, and all their calculative functions(addition, negation, dot product, scalar product,perpendicular eqn of a line, parallel eqn of a line). _Plus for the ease of use of geometry_, I have implemented **translation, rotation, scaling** etc functions for the above classes. If permitted, I would like to add them in a new file dedicated towards C/C++ developers.
