 * Makes a shallow clone of an object, setting or overriding the specified

 * **Note:** If property in the object is equal to value by reference then function
 * just returns object without changes
 *
 * @param {String} prop The property name to set
 * @param {Function} fn The function to execute
 * @param {Object} obj The object to clone
 * @return {Object} A new object equivalent to the original except for the changed property.
 * @example
 *
 *      propSetBy('a', x => x+1, {a: 1}); //=> {a: 2}
