DataList

class DataList<DataT>(initialData: DataT)

Represents a list of data items. Supports three operations:

add: Adds data to the end of the list
remove: Removes the given item from the list, returns current last element and indication if the removed element was last.
last: Returns last element in the list, or initialData if the list is empty.

This structure is NOT thread-safe. Synchronization should be performed externally.
