Code CleanUp

It works fine.
Calculate Insulation

This is now a separate function. It can be modified with the preferred

Fixed the surface properties bug

Now we can extract transparency and temperature from the surfaces that
WE define
Radiation calculation upgrade

We have introduced:
- better organization of the radiation calculation
- added ground reflection
- Insolation now is an independent function
- Added reflected radiation based on Rayman
- Added definition and inclusion of view factors to amend the radiation
calculation
- added sky view factor in the calculation of the grid nodes
- amended functionangle_between_vectors
- updated calculation of radiation based on ASHRAE
- Fixed dealing with transparency and temperatures of surfaces
- General bug fixes and clean up
