Add a general-purpose controller for UI elements which
have 'click-away' behavior; that is, they should be
deactivated on document clicks.
This generalizes existing behavior added for the Create
menu, such that it may be used on other, similar menus
and UI elements.
Part of ongoing transition of common user interface
components, WTD-574.
Add general structure for Open MCT Web, including
top-level and second-level directory structure.
README files are included to explain the role of
each directory; markdown is used to allow for
richer display when viewer support is present.
