TASK
Write a transformation Class that allows 3 types of transformation .. translation, rotation and scaling All in 2D with homogeneous coordinates
//Transformation T(rotation, angle);
//Transformation T2(Scale, sx,sy,) ;
//TransformationT3(translate, tx, ty) ;

//My3DVector V(1.34,2.21,1) ;
//My3DVector RptatedVec = T*V
//My3DVector ScaledVec = T2*V
//My3DVector TranslatedVec = T3*V

Hints 
First create a new editor with class transformation
Then Inside the class have a matrix from my3D matrix object as data member 
Depending on the first argument, fill the matrix elements appropriately
Overload the *operator so it takes Transformation object and My3DVector as argument types. Multiply the matrix that is inside the transformation object with the given My3DVector
