docs: Checks if `value` is a plain object, that is, an object created by the
  `Object` constructor or one with a `[[Prototype]]` of `null`.
  
  **Note:** This method assumes objects created by the `Object` constructor
  have no inherited enumerable properties.

  @param {*} value The value to check.
  @returns {boolean} Returns `true` if `value` is a plain object, else `false`.
  @example
  
  function Foo() {
  this.a = 1;
  }
  
  _.isPlainObject(new Foo);
  // => false
  
  _.isPlainObject([1, 2, 3]);
  // => false
  
  _.isPlainObject({ 'x': 0, 'y': 0 });
  // => true
  
  _.isPlainObject(Object.create(null));
  // => true
