Overview

Each airspace has one or more layers with optional airspace class and mandatory vertical limit.

layer = AIXM.layer(
  class: String or nil
  location_indicator: String or nil
  vertical_limit: AIXM.vertical_limit
)
layer.activity = String or nil
layer.timetable = AIXM.timetable or nil
layer.selective = true or false (default)
layer.remarks = String or nil
airspace.add_service(AIXM.service)
