> We should introduce a method that takes a class of UDF instead of an instance similar to:
> {code}
> TableEnvironment#createTemporarySystemFunction(String name, Class<? extends UserDefinedFunction> functionClass);
> {code}
> The API should look like:
> {code}
> public static ApiExpression Expressions:call(Class<? extends UserDefinedFunction> function, Object... arguments)
> {code}
> *Important:* Update the javadocs in {{*Table}} as well.
