Destroy representation scope before adding elements back into
the DOM; avoids having a momentary activation of watches and
listeners on those scopes before they are replaced with newly
compiled content for new scopes.
Create new scopes on every changeTemplate request, even if
the same template is being viewed; presume that we want a
new instance of the same template. Avoids scope reuse for
cases such as switching from a plot of one object to a
plot of another object.
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.)
