cue init

[Chuck]

• The first statement in the .init cue must be base.init or .init
• If the signature is the same as an inherited one then is override or a base.init call is required, just like methods.
• init can be overloaded just like a method.
• init cannot be invoked outside of an init cue (other than indirectly through instantiation)
• If no init cues are defined in a class then the init cues of the base class are inherited.
• At some point def init should give a warning.
• At some point the internal hacks around methods called init can be removed.

• Done: def init should give a warning.
• To do: If a subclass defines no init and there is no parameterless init in the base class, give the user a nice error message with correct line number.
