Really sticky collection view layout
// The issue with sectionHeadersPinToVisibleBounds and sectionFootersPinToVisibleBounds is that they do not pin
// first header and last footer when bouncing. This layout subclass fixes that.

Xamarin Reduce App Size
* Reducing executable size:
http://developer.xamarin.com/guides/cross-platform/deployment,_testing,_and_metrics/memory_perf_best_practices/#Reducing_Executable_Size
* Use the linker (iOS [1], Android [2]) to remove unnecessary code from your assemblies
[1] https://developer.xamarin.com/guides/ios/advanced_topics/linker
[2] https://developer.xamarin.com/guides/android/advanced_topics/linking
* Reference third-party libraries judiciously
* Applying constraints to generics may reduce app size, since less code would need to be included (haven’t verified this)
