/**
 * Injects method into an object. optionally preserving access to the original method via "`super`" and original instance via "`self`".
 *
 * **Note**:
 *
 * * In the new method, you can use `this.super()` to call the original method, `this.super()` is already bound with original instance.
 * * The `this[aMethodName]` is also the original method, but not bound yet.
 * * `this.self` is the original instance!
 *
 * @param {object} aObject the target object to inject
 * @param {string} aMethodName the target method to inject
 * @param {Function} aNewMethod the new method to be injected into the aObject.
 * @returns {boolean} whether the injection is successful.
 *
 * @example
 * var obj = {
 *   method1: function() {
 *     console.log('Hello');
 *   }
 * };
 *
 * var newMethod = function() {
 *   this.super();
 *   console.log('World');
 * };
 *
 * injectMethod(obj, 'method1', newMethod);
 *
 * obj.method1(); // Output: Hello\nWorld
