Prevent overloading of constructor (no-constructor)

Backbone Models, Views and Collections use constructor method to instantiate themselves. Overloading it might lead to unexpected results. When overloading constructor, you should always call base. In most cases it's easier to overload initialize method, which will be executed when Model, View or Collection is created.

Rule Details

The following patterns are considered warnings:

Backbone.Model.extend({
	constructor: function() {
		...
	}
});

The following patterns are not warnings:

Backbone.Model.extend({
	initialize: function() {
		 ...
	}
});

When Not To Use It

If you are creating your own wrapper around Model, View or Collection, it's probably better to overload constructor. So this rule should be disabled for those files.
