• New decission_tree() function to create a perfect decision tree based on a set of observations and (if selected) see the step-by-step procedure;
• New multivariate_linear_regression() function to generate linear equation lines that approximate the values on a set of observations and (if selected) see the step-by-step procedure;
• New polynomial_regression() function to generate polynomial equation lines that approximate the values on a set of observations to selected degree and (if selected) see the step-by-step procedure;
• New perceptron() function to calculate the weights of a perceptron and predict values on a set of observations and (if selected) see the step-by-step procedure;
• New knn() function to perform k-nearest neighbors classification on a set of observations and (if selected) see the step-by-step procedure;
• New print.tree_struct() function that prints a tree with the structure of the output of the decision_tree() function;
