 * @method deprecate
 * @param {Function} [fallbackMethod=null] A method to call when the deprecated method is used. See the example for how
 * @param {String} [name=null] The name of the method or property to display in the console warning.
 * to deprecate properties.
 * @return {Function} If a fallbackMethod is supplied, returns a closure that will call the fallback method after
 * logging the warning in the console.
