GTL 3D ternplot

This is an upgrade of the 2D ternplot code (ID#38241).

Here the 'main_3D.m' code plots relationship between four chemical compositions of GTL (normal-paraffin, iso-paraffin, aromatics and cyclo-paraffin).
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.
