OverlayPlot: can be used on any domain object that has or delegates a telemetry capability.
StackedPlot: can be used on any domain object that delegates telemetry or delegates composition of elements that have telemetry.

Directives

mct-chart: an element that takes series, viewport, and rectangles and plots the data. Adding points to a series after it has been initially plotted can be done either by recreating the series object or by broadcasting "series:data:add" with arguments event, seriesIndex, points. This will append points to the series at index seriesIndex.
mct-plot: A directive that wraps a mct-chart and handles user interactions with that plot. It emits events that a parent view can use for coordinating functionality:
- emits a user:viewport:change:start event when the viewport begins being changed by a user, to allow any parent controller to prevent viewport modifications while the user is interacting with the plot.
- emits a user:viewport:change:end event when the user has finished changing the viewport. This allows a controller on a parent scope to track viewport history and provide any necessary functionality around viewport changes, e.g. viewport history.
mct-overlay-plot: A directive that takes domainObject and plots either a single series of data (in the case of a single telemetry object) or multiple series of data (in the case of a object which delegates telemetry).

Controllers

NOTE: this section not accurate. Essentially, these controllers format data for the mct-chart directive. They also handle live viewport updating, as well as managing all transformations from domain objects to views.

StackPlotController: Uses the composition capability of a StackPlot domain object to retrieve SubPlots and render them with individual PlotControllers.
PlotController: Uses either a domain object that delegates telemetry or a domain object with telemetry to and feeds that data to the mct-chart directive.

TODOS:

Re-implement history stack.
Re-implement plot pallette.
Re-implement stacked plot viewport synchronization (share viewport object)
Other things?
Handle edge cases with marquee zoom/panning.
Tidy code.
