Checks if `value` is a plain object, that is, an object created by the
`Object` constructor or one with a `[[Prototype]]` of `null`.

@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
