-Each configuration has an fcid (FlightConfigurationId)
-FlightConfigurationID is a new type.
- small wrapper class around String
- provides better traceability, error detection, readability
- the fcid is now the hashMap key for any FlightConfigurationSet
-rename Configuration => FlightConfiguration (to be more explicit about class purpose)
-combine MotorInstance =><= motorConfiguration
-Refactor ThrustCurveMotorInstance into an outer public class
-MotorId => (ren) => MotorInstanceID
-fold IgnitionConfiguration => <MotorInstance>.<IgnitionConfiguration>
-Created IgnitionEvent class
-Implemented partial checking for file version 1.8
-rename FlightConfigurationImpl => FlightConfigurationSet
-rename MotorFlightConfigurationImpl => MotorConfigurationSet
- Rockets now list all configurations
-implemented a FlightConfigurationSet of FlightConfigurations
