help system improvements
The REOT group identifed some upgrades to the help system in Morpho as being
high priority. In particular, they wanted to see a searchable help system and
an index. This should include both the morpho documentation and the EML
documentation. We should also be sure thatthe EML documentation is available
from within Morpho, both in the editing environments (e.g., package wizard,
editor, Jalama) and as a separate section in the help menu.
