May end up using this in some other project but for now it's just an application of the crossing number raycast algorithm in Fortran

• Assign all twelve zones with associated vertices
• Line intercept function
• Get potential zones based on closest vertices to intercept point
• Cast function which imitates a straight line and checks if it intercepts the edges of closest polygon(s)
• Function to deallocate points
