Work around normal behavior of Angular when path changes;
instead of reinstantiating controller for Browse mode
when Browse-initiated path changes occur, act as if the
route hadn't changed (so that the URL updates but the
currently-displayed state, e.g. tree expansion, is
preserved.) WTD-1149.
Set validity of selected location from locator control, to
disallow creation when no valid location is selected (which
is possible due to containment rules.) WTD-962.
Refactor view switcher to simplify it; treat it
as a representation of a domain object that modifies
an ng-model. This simplifies reuse, e.g. in frames
within a layout. 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.
Fill in spec for the controller which maintains a set of
applicable and selected view options to populate the
view switcher. Part of Browse mode and, in turn, part
of the common user interface elements that are being
transitioned for WTD-574.
Add in-line docs for bundle platform/commonUI/browse,
which implements Browse mode, one of the common user
interface bundles being transitioned in WTD-574.
Add JSDoc to Create-related classes and remove the
UUIDService (replaced by third-party lib) to reduce
amount of code to cover and prepare for code review,
as part of ongoing transition of common user interface
elements, WTD-574.
Add JSDoc and clarifying comments to the CreateMenuController,
which is responsible for maintaining an up-to-date set of
Create actions for a given domain object. WTD-574.
