Sector naming conventions

"The main aim of this project was to understand how sectors in the E:D galaxy are named, and to be able to predict a system's location (at least approximately) given only its name.

This would allow for other tools (such as EDSM) to have sanity-checking on user-provided coordinates, and would also allow historical flight logs to be filled in with approximate locations. It would also be useful in other situations where approximate coordinates for a system are required without access to the galaxy map, such as Fuel Rat dispatching."
