/**
 * Given a function that generates a key, turns a list of objects into an
 * object indexing the objects by the given key. Note that if multiple
 * objects generate the same value for the indexing key only the last value
 * will be included in the generated object.
 *
 * Acts as a transducer if a transformer is given in list position.
 *
 * @func
 * @memberOf R
 * @since v0.19.0
 * @category List
 * @sig (a -> String) -> [{k: v}] -> {k: {k: v}}
 * @param {Function} fn Function :: a -> String
 * @param {Array} array The array of objects to index
 * @return {Object} An object indexing each array element by the given property.
 * @example
 *
 *      const list = [{id: 'xyz', title: 'A'}, {id: 'abc', title: 'B'}];
 *      R.indexBy(R.prop('id'), list);
 *      //=> {abc: {id: 'abc', title: 'B'}, xyz: {id: 'xyz', title: 'A'}}
