...when determining if a representation needs to be
refreshed. Avoids representations becoming stale
when switching or navigating among linked instances
of the same domain object.

An mct-representation may have a refresh triggered either by
a key change or a domain object change; both will typically
happen in the same digest cycle. Track what prior state was
an abort refreshes if nothing will change.
Handle edge cases (e.g. directive priorities, race conditions)
to ensure that mct-representation and mct-include display correctly
when added to or removed from the DOM.
...of templateLinker into mct-representation. Not working currently
due to prevalence of mct-representation instances with transcluding
directives (hitting a multiple transclusion error.)
Invoke the destroy methods of any active representers when
a scope is destroyed; supports time controller, which needs
to accurately track when it has or hasn't been attached to
a view. WTD-1515
Trust resource URLs to skip SCE-checking (which profiling
flags as a performance problem) for mct-include and
mct-representation; these URLs are pulled from bundles and
not user-entered, so should be trusted. WTD-1256.
When switching among domain objects and/or views, avoid
reusing the same information is scope. The wrong information
in scope can cause various failures in views, such as WTD-1182.
When changes to a domain object's modification timestamp are
detected, refresh only the capabilities associated with that
domain object (instead of rebuilding the whole view.)
Specifically avoids latency when layout views are rebuilt,
WTD-716.
Perform initial population of scope in mct-representation
at link time, instead of waiting for watches to be fired;
this avoids the need for extra digest iterations, which
Angular detects as indicators of infinite loops (throwing
exceptions accordingly.) Fixed in the context of supporting
transition of editable Layouts, because these errors were
being thrown upon exiting Edit mode. WTD-535.
Add representers as a category of extension; these are extra
steps to perform when representing a domain object. This
will be used to support automatic mutation/persistence of
domain objects from a watch, while avoiding bloat within
the mct-representation directive itself. This, in turn,
simplifies the persistence strategy to be employed by
Layout views when editing concludes. WTD-535.
Use ng-model when communicating state to/from the
tree in browse mode. This will simplify implementation
of the Locator control, which also uses a tree, but
which should not set navigation state. WTD-593.
Add spec for the mct-representation; separate out gesture
attachment to improve testability and increase cohesion.
Part of ongoing initial authorship of representation
component, WTD-521.
