> Currently, each Stellar function handles validation of required function parameters in its own way.  In some cases, we have functions that throw an IndexOutOfBoundsException, in other cases the function will produce its own error message and exception.
> There needs to be a standard mechanism to validate required function parameters.  This mechanism should handle missing parameters gracefully and provide an error message that makes sense to a user.
