Handle super Constructor delegation

[sergiotaborda]

A constructor always must call another constructor until the primary constructor is called. When A inherits from B the constructor of B must be called at some point in the chain. The programmer may explicitly declare where the super constructor should be called

class A extends B {

constructor A () extends B()

}

(in java backend constructors are final static methods )

Is necessary to define how to access the object the super constructor created

[sergiotaborda]

Constructor extensions cannot call methods (currently). Data must be passed directly.

public class AssertionException extends Exception {

    public constructor ();

    public constructor (message : String) extends super (message); 
}

named constructors must be handled
