Class	Description
ChangeType	Change types.
VirtualArray	Advanced array like class that helps loading items on demand. Use "length" property to specify total number of items,
"loadSize" to specify number of items to be requested in a single request, "itemsLoading" event to handle items request and
"load()" method to copy items into the array. All already loaded items are cached in-memory and when "getItem()" method is called
the array will raise "itemsLoading" event for still not loaded items. Example:
var virtualArray = new VirtualArray<number>(100);
virtualArray.loadSize = 15;
virtualArray.on("itemsLoading", (args: virtualArrayDef.ItemsLoading) => {

var itemsToLoad = new Array<number>();
for (var i = 0; i < args.count; i++) {
    itemsToLoad.push(args.index + i);
}
virtualArray.load(args.index, itemsToLoad);

});
