getItemHeight is called excessively #8

Hi @jsoendermann! Thanks for building this helper.

I'm curious why getItemHeight is called so often. If I put a console.count, it clearly shows that all items in the list are measured multiple times whenever a new item is appended.

Is this just the way VirtualizedLists work in React Native?

Yes, I believe that's a VirtualizedList issue
