/**
 * Iterate over an input `object`, calling a provided function `fn` for each
 * key and value in the object.
 *
 * `fn` receives three argument: *(value, key, obj)*.
 *
 * @func
 * @memberOf R
 * @since v0.23.0
 * @category Object
 * @sig ((a, String, StrMap a) -> Any) -> StrMap a -> StrMap a
 * @param {Function} fn The function to invoke. Receives three argument, `value`, `key`, `obj`.
 * @param {Object} obj The object to iterate over.
 * @return {Object} The original object.
 * @example
 *
 *      const printKeyConcatValue = (value, key) => console.log(key + ':' + value);
 *      R.forEachObjIndexed(printKeyConcatValue, {x: 1, y: 2}); //=> {x: 1, y: 2}
 *      // logs x:1
 *      // logs y:2
 * @symb R.forEachObjIndexed(f, {x: a, y: b}) = {x: a, y: b}
