Add typedefs relevant to the date aggregator; in particular,
document properties used to determine how to format timestamps
associated with a telemetry point.
When viewing an event message generator new messages are now added to the
bottom of the display, rather than being added to the top and pushing
the other messages down by one. #18.
Remove linear search for unused positions when queuing telemetry
updates; instead, track available positions such that insertion
is more performant at a modest cost (bound to the number of subscriptions)
of retrieval. Additionally, add implementation notes in-line.
WTD-1202.
Change the path used to import moment for the telemetryFormatter.
Previously, a relative path was used; since telemetryFormatter was
initially implemented, however, moment has been made available as
simply moment by require configuration changes elsewhere. Inconsistent
usage of moment here can result in load timeouts under certain
script load orderings. Changed in the context of WTD-884 (which does
use moment elsewhere.)
Begin adding a general purpose handler for telemetry which
extends on the behavior associated with the telemetrySubscriber
by supporting access to historical data as well. WTD-806.
Update spec for TelemetrySubscription to account for the fact
that it initially calls back when the set of telemetry objects
is available (which supports views such as Fixed Position
which want to defer all telemetry-handling responsibility to
the subscription.) WTD-879.
Fire callback from telemetry subscriber when the set of
object references changes. This allows views which use
the subscriber to register one callback, while still
ensuring that they are notified when there is new
information to show. Supports fixed position view, WTD-879.
Merge in work-in-progress for WTD-615 (Fixed Position View)
into topic branch for WTD-889 (a sub-issue of WTD-615, which
has been broken down into discrete chunks to support
development.

Implement data structures which support lossless/lossy
behaviors for telemetry subscriptions (that is, allow
users of the telemetrySubscriber to decide whether or not
they are willing to drop updates in favor of only being
notified with the latest available values.) WTD-784.
Add specs for data structures which will support resolution
of WTD-784 by retaining all data not yet received by callbacks
(instead of just the very latest) such that plots can ensure
they do not miss streaming data.
Add a test case for subscriptions which should be handled
losslessly (that is, which should notify subscribers once
per data event, not once per execution cycle.) This
test case reflects the underlying cause for WTD-784.
