Size of new code in this package:

be-oosoom is a be-decorated-based decorator/behavior that monitors the visibility of the element it adorns. When the visibility changes, it:

1. Checks if the element it adorns has property "beOosoom"
2. Checks if any other decorators/behaviors adorning the element have virtual property "beOosoom"

For both scenarios, be-oosoom expects the beOosoom property it finds to be a string-valued key to a boolean property that is used by the component or behavior to indicate whether to be "actively engaged" or not. be-oosoom sets the property to true when the element is visible, false when it scrolls out of view (or gets hidden via a details section being closed, for example). If the string starts with ! then the property name after the ! indicates "hibernating" mode, so be-oosoom does the opposite.
