Issue Description:

Some initializers' implementation is quite expectable, e.g. a field-wise naive initializer. Thus, we can implement an automated refactoring to help developers adding such initializer, e.g.

// Right click on Animal and apply "add field-wise init" refactoring
class Animal {
  var age: Int
  var kind: AnimalKind
  var gender: Gender
}

An available refactoring "add field-wise init" shows up when the user right clicks the declared name Animal. After applying the local refactoring, the code snippet transforms to:

// code placeholder
class Animal {
  var age: Int
  var kind: AnimalKind
  var gender: Gender

  // Auto-generated initializer
  init(age: Int, kind: AnimalKind, gender: Gender) {
    self.age = age
    self.kind = kind
    self.gender = gender
  }
}

I'm trying to solve this as my starter bug... Could somebody please guide me on where to start with this?

@nkcsgexi I will be starting work on this in the next day or two. I think this will be pretty quick as I can use everything I learn't from my recently closed PR... I will have to figure out how to get the correct location in the source code to write out the initializer...
