/**
* Creates a function that invokes `func` with the arguments of the created
* function. If `func` is a property name the created callback returns the
* property value for a given element. If `func` is an object the created
* callback returns `true` for elements that contain the equivalent object properties, otherwise it returns `false`.
*
* @static
* @memberOf _
* @category Util
* @param {*} [func=_.identity] The value to convert to a callback.
* @returns {Function} Returns the callback.
* @example
*
* var users = [
* { 'user': 'barney', 'age': 36 },
* { 'user': 'fred', 'age': 40 }
* ];
*
* // Create custom iteratee shorthands.
* _.iteratee = _.wrap(_.iteratee, function(callback, func) {
