Updated lines 9 & 10 with the converting of v1 and v2 into numpy arrays. Also, the Object behavior / Method vector_add with self.v1 + self.v2 (line 17). And the underlying Object behavior / Method plot_vector_add with numpy array removal in declarations, echoing functionality deriving from numpy array declarations in lines 9 & 10
