3D ternplot

This is the 3D update ternplot of "GTL jetfuel_ternplot with neural network".

This is the 3D update of "GTL jetfuel_ternplot with neural network". "main_3D.m" code plots relationship between four chemical compositions of GTL (normal-paraffin, iso-paraffin, cyclo-paraffin and aromatics).

I like to thank this author Carl Sandrock for his amazing code base on what this upgrade is made. I also thank Dr.Ehsan Elborzi (Shelfield university) for his contribution and Dr.Nimir Elbashir (texas A&M university) for his support in providing GTL research data that this code is using to plot.
