Refactored sorting. Added test to verify all horizon areas (outside exceptions) are marked as station areas. Added test to verify shuttle areas are not marked as station areas. Refactored how the area sorting var is made and used. Added a global list of all areas.

* ## Lazylists
|
|
*
|
|
* * What is a lazylist?
|
|
*
|
|
* True to its name a lazylist is a lazy instantiated list.
|
|
* It is a list that is only created when necessary (when it has elements) and is null when empty.
|
|
*
|
|
* * Why use a lazylist?
|
|
*
|
|
* Lazylists save memory - an empty list that is never used takes up more memory than just `null`.
|
|
*
|
|
* * When to use a lazylist?
|
|
*
|
|
* Lazylists are best used on hot types when making lists that are not always used.
|
|
*
|
|
* For example, if you were adding a list to all atoms that tracks the names of people who touched it,
|
|
* you would want to use a lazylist because most atoms will never be touched by anyone.
|
|
*
|
|
* * How do I use a lazylist?
|
|
*
|
|
* A lazylist is just a list you defined as `null` rather than `list()`.
|
|
* Then, you use the LAZY* macros to interact with it, which are essentially null-safe ways to interact with a list.
|
|
*
|
|
* Note that you probably should not be using these macros if your list is not a lazylist.
|
|
* This will obfuscate the code and make it a bit harder to read and debug.
|
|
*
|
|
* Generally speaking you shouldn't be checking if your lazylist is `null` yourself, the macros will do that for you.
|
|
* Remember that LAZYLEN (and by extension, length) will return 0 if the list is null.
