Default template should not render collapsed children

[jtrussell]

I.e. the second suggestion here should just be the default.

Probably should address #84.

Is Angular's bind-once syntx the best workaround for the performance now?

[jtrussell]

Using ng-if to not render collapsed children can give a huge performance boost - bind-once would be interesting to experiment with.

Ok,so the next work is using ng-if to not render collapsed children for the v2.

[jtrussell]

Yep, the bulk of the work will be in updating the tests to not rely on a particular template - many tests will break with this change :(.

[kuroky360]

Thanks for your all effort !

[jtrussell]

Feel free to dig in if you like :). You can submit PR's against the v2 branch.

[kuroky360]

Yes,I will ~

@kuroky360 any progress with the performance boost? I'm hitting the limit too and the improvement would be very appreciated

[kuroky360]

@fhurta sorry for that
