// Create a class called 'Matrix' containing constructor that initializes the number of rows and the number of columns of a new Matrix object. The Matrix class has the following information:
// 1 - number of rows of matrix
// 2 - number of columns of matrix
// 3 - elements of matrix (You can use 2D vector)
// The Matrix class has functions for each of the following:
// 1 - get the number of rows
// 2 - get the number of columns
// 3 - set the elements of the matrix at a given position (i,j)
// 4 - adding two matrices.
// 5 - multiplying the two matrices
// You can assume that the dimensions are correct for the multiplication and addition.
