/**
 * Makes a shallow clone of an object, setting or overriding the nodes required
 * to create the given path, and placing the specific value at the tail end of
 * that path. Note that this copies and flattens prototype properties onto the
 * new object as well. All non-primitive properties are copied by reference.
 *
 * @func
 * @memberOf R
 * @since v0.8.0
 * @category Object
 * @typedefn Idx = String | Int
 * @sig [Idx] -> a -> {a} -> {a}
 * @param {Array} path the path to set
 * @param {*} val The new value
 * @param {Object} obj The object to clone
 * @return {Object} A new object equivalent to the original except along the specified path.
 * @see R.dissocPath
 * @example
 *
 *      R.assocPath(['a', 'b', 'c'], 42, {a: {b: {c: 0}}}); //=> {a: {b: {c: 42}}}
 *
 *      // Any missing or non-object keys in path will be overridden
 *      R.assocPath(['a', 'b', 'c'], 42, {a: 5}); //=> {a: {b: {c: 42}}}
