Deactive mct-resize when its containing scope is destroyed;
that is, don't go on polling for size changes indefinitely.
Issue discovered/addressed in the context of investigating
sluggishness of plotting in WTD-717.
Add a service to wrap Date.now(), such that this can be injected
(simplifying testing of scripts which need to respond to system
time.) Specifically supports staleness indication, WTD-660.
Merge latest from master branch into topic branch for separating
out Couch adapter from persistence cache, in support of reusing
the latter for the WARP persistence adapter, WTD-702.
Remove reference to persistence cache from the Couch adapter's
bundle definition; this has been moved into a separate bundle
to support reuse with the WARP Server persistence adapter,
WTD-702.
Move cache sources into their own bundle, for reuse with other
persistence adapters; specifically supports the persistence
adapter to the WARP Server, which is non-Couch but which will
want to use this cache. WTD-702.
Update README files to document the reorganization of persistence
sources into separate bundles for the Couch adapter and for the
persistence cache, in support of reusing the latter with a
different persistence adapter, WTD-702.
Move persistence sources into a deeper bundle in preparation for
splitting of persistence into two bundles - one specific to the
Couch adapter, and one for persistence caching generally. This
supports WTD-702, the WARP persistence adapter, which will not
use Couch for persistence but which will want to use the platform-
provided persistence cache.
Allow callback provided when subscribing to telemetry using
telemetrySubscriber to be omitted; this permits usage of
the resulting subscription more directly from controllers,
such as for fixed position view, WTD-615.
Add tests and JSDoc to the style sheet loader introduced to
allow bundles to introduce their own CSS files through the
platform's regular extension mechanism; WTD-591.
Implement 'runs' as a built-in category of extension, to support
bundle addition of functions to run when the application first
starts. Specifically supports loading of stylesheets, WTD-591.
Add tests for a built-in extension type to framework to allow app.run
to be invoked via bundle extensions. This supports stylesheet
injection, which should happen on load but isn't triggered
from any particular part of the page. WTD-591.
