Support calling super methods

[hasanaburayyan]

Feature Spec

Wing now supports calling methods from inherited classes within derived classes with super.

class Student {
  name: str;
  major: str;
  init(name: str, major: str) {
    this.name = name;
    this.major = major;
  }
  
  toString(): str {
    return "Name: ${this.name}, Major: ${this.major}";
  }
}

class PaidStudent {
  hrlyWage: num;
  
  init(name: str, major: str, hrlyWage: num) {
    super(name, major);
    this.hrlyWage = hrlyWage;
  }

  // Overridden method that calls method on super
  toString(): str {
    return "${super.toString()}, hrlyWage: ${this.hrlyWage}";  
  }
}

@staycoolcall911 this needs to be p1. We can't really extend anything without this.

@eladb I think it might fall into p1 territory as well. Right now you can still access methods on the super class with this.someMethod() but this is troublesome and just hacky for overriding methods. It would require you to do something like

class A {
	init() {}
	toString(): str {
		return "parent";
     }
}

class B extends A {
   init() { super() }

  toStringNotOverriden() {
    return this.toString() + " child";
   }
}
