Add a spec for an editable model cache; this will behave
similarly to the existing domain object cache, except
that it will cache only models. Use of this will permit
multiple instances of editable objects to be created with
unique contexts (that is, distinct parent objects accessible
via the context capability) which in turn will avoid the
ambiguous parentage which results in unexpected behavior of
the Remove action in Edit mode, WTD-473.
Add entries for new scripts to test suites, to ensure
tests fail until scripts added to support transition
of Layout object/view (WTD-535) have been completed.
WTD-535.
Add specs for remaining capabilities and capability
wrappers employed by Edit mode. Completes coverage
for bundle platform/commonUI/edit, which is being
transitioned along with other commonUI bundles in
WTD-574.
Add specs for the save and cancel conclude-editing
actions, part of bundle platform/commonUI/edit
(Edit Mode) which is transitioned among the various
common UI bundles. WTD-574
