Add libraries for Angular and Require. This expands
folder structure to support initial build (WTD-519)
and also directly supports implementation of a
framework layer (WTD-518).
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.
