			* This method is like `_.assignIn` except that it accepts `customizer`
			* which is invoked to produce the assigned values. If `customizer` returns
			* `undefined`, assignment is handled by the method instead. The `customizer`
			* is invoked with five arguments: (objValue, srcValue, key, object, source).
			*
			* Note: This method mutates `object`.

			* @param {Object} object The destination object.
			* @param {...Object} sources The source objects.
			* @param {Function} [customizer] The function to customize assigned values.
			* @returns {Object} Returns `object`.

			* @example

			* function customizer(objValue, srcValue) {
