function plot3rgb(P)
%-DESCRIPTION------------------------------------------------------------------------
% This function plot a colored 3-dimensional line of a set of given points. The plot
% varies its color in a form, x axis as red, y as green and z axis as blue.
% So basically if the plot proceeds in x-axis it will colored as red, if proceed in
% y-axis it is colored as green and if proceed in z-axis then its colored as blue.
% INPUT: It take a matrix that contains a set of vectors.
