/**
 * Removes all elements from an array that the callback returns truey for
 * and returns an array of removed elements. The callback is bound to `thisArg`
 * and invoked with three arguments; (value, index, array).
 *
 * 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 Arrays
 * @param {Array} array The array to modify.
 * @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 {Array} Returns a new array of removed elements.
 * @example
 *
 * var array = [1, 2, 3, 4, 5, 6];
 * var evens = _.remove(array, function(num) { return num % 2 == 0; });
 *
 * console.log(array);

 * // => [2, 4, 6]
