WindowState

class WindowState[T] extends MonoidState[T]

this is a list of states, each of which is bounded by a time window state of each window doesn't affect each other

WindowState requires a Algebird Group to be passed in Group augments Monoid with a minus function which makes it possible to undo the update by messages that have left the window
