Use GlobalAttention as GraphLevelClassifier

[vlatorre847]

I wanted to use the GlobalAttention layer as graph level classifier instead of the more standard global_mean_pool or global_max_pool. However I noticed that its implementation is more complex than the aforementioned methods.

Is there any example I can use as reference? I searched the examples but I could not find anything.

We have an example of GlobalAttention here :)
