/**
* 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}}}
