Suppose you have a "nearly" constant value in a custom polymer-element.
You use the [[..]] to minimize monitoring. But in some rare cases, you
the user needs to change this value via a javascript function.
Is there a function which the script that changes the value can notify polymer
that this value has changed, so that all of its references will be updated?
I am thinking about something like printer name, or building location information.
It is normally not changed, but only on very special instances. This
way the page could be static, and storing user specific information
could be stored in local storage and retrieved by the "ready" callBack.
In that routine, the user's data could be used to customize what
is really very static data.
