ProxyFlex Class
This class manages a ScrollView and its Flex by adding virtualization to its items.
This discharge the Flex from having to handle a big number of children. Instead, it has a small number of children and the ProxyFlex handles the large amount of ProxyController<ControllerType>. This is mostly a work around poor performance of handling and refreshing a large amount of UI objects in the scene.
