Rough Draft of Parabolic Method

What needs to be implemented left is how to loop it; a do while will do
:)
- MUCH PUBLIC VARIABLES ;_;
- setprecision for testing purposes
- parabolic_vertex for checking Aopt,eopt, Aoptopt, eoptopt and so on
- renamed AandE to PA for easier typing
- added parabolic_check and PA_check for parabolic_vertex()
- Aopt, eopt for parabolic_vertex()
- main contains rough draft of loop
- edited Hades' xlsx file for more accuracy.
