Exception thrown on undefined data values

[UppaJung]

Vento (via the JS enginge?) throws an exception if a value isn't defined.

Hence, if a is undefined and b is set to "foo", one would expect a ?? b or a || b to result in foo, but instead it results in an exception.

My workaround for problems like title being undefined has been to make sure everything that uses the template has an empty string assigned to title

title:

Yes, this is how JavaScript works and I think there's no way to call an undefined variable without throwing an error.

If you don't care if a variable is defined or not, use {{ it.varname }} instead of {{ varname }}. The it global variable contains all defined variables.

As of #43, this issue is fixed. @UppaJung give it a try once the new version is published.
