/**
 * Creates an object composed of keys generated from the results of running
 * each element of the collection through the given callback. The corresponding
 * value of each key is the last element responsible for generating the key.
 * The callback is bound to `thisArg` and invoked with three arguments;
 * (value, index|key, collection).
 *
 * If a property name is provided for `callback` the created "_.pluck" style
 * callback will return the property value of the given element.
 *
 * If an object is provided for `callback` the created "_.where" style callback
 * will return `true` for elements that have the properties of the given object,
 * else `false`.
 *
 * @static
 * @memberOf _
 * @category Collections
 * @param {Array|Object|string} collection The collection to iterate over.
 * @param {Function|Object|string} [callback=identity] The function called
 *  per iteration. If a property name or object is provided it will be used
 *  to create a "_.pluck" or "_.where" style callback, respectively.
 * @param {*} [thisArg] The `this` binding of `callback`.
 * @returns {Object} Returns the composed aggregate object.
 * @example
 *
 * var keys = [
 *   { 'dir': 'left', 'code': 97 },
 *   { 'dir': 'right', 'code': 100 }
 * ];
 *
 * _.indexBy(keys, 'dir');
 * // => { 'left': { 'dir': 'left', 'code': 97 }, 'right': { 'dir': 'right', 'code': 100 } }
 *
 * _.indexBy(keys, function(key) { return String.fromCharCode(key.code); });
 * // => { 'a': { 'dir': 'left', 'code': 97 }, 'd': { 'dir': 'right', 'code': 100 } }
 *
 * _.indexBy(characters, function(key) { this.fromCharCode(key.code); }, String);
 * // => { 'a': { 'dir': 'left', 'code': 97 }, 'd': { 'dir': 'right', 'code': 100 } }
