Vanilla Linear Regression Model optimized via Vanilla Gradient Descent Method

A simple demo for Vanilla Linear Regression Model optimized via Vanilla Gradient Descent Method

This is a very simple demo for Vanilla Linear Regression Model (LRM) optimized via Vanilla Gradient Descent Method (GDM) on 1-D and 2-D data set. NOTE that the multicollinearity case is unexpectedly shown. A More advanced version is expected in the coming future. Anyway, JUST FOR FUN!
