.Evolving an Application:  Data Entry Dialog, encapsulated w/Edit mode

COMMENTS
--------
Okay, we've managed to accomplish a number of things:

(1) We've created a dialog object which handles all record events
    internally; it's "encapsulated".

(2) We've added an "Edit mode", which:
    (a) Beeps on keyboard input, unless the user activates "Edit".
    (b) Turns on "StaticText", which tells use how to move from field
        to field.
    (c) Sets the screen's border color (color systems only).

(3) Hints are now "off" when not editing.
    The "GetHelpCtx" method for the object will return "hcNoContext"
    when NOT in "Edit" mode.  This will turn off hints, since the
    StatusLine is context sensitive.

NOTE - Now, there is no new "Application^.HandleEvent", since all
events (so far) in this application are encapsulated.


UPSIDE
------
The user can't accidentally over-write data; they've gotta
deliberately activate "Edit" mode by pressing "F2".  They can still
browse the database, whether in "Edit" or "View" mode.


DOWNSIDE
--------
Gosh, darn it - we forgot a ScrollBar!  What kind of Application are
you writing here, anyhow?  And the user did WHAT!  Closed the dialog
while in Edit mode?  Sigh...ok, let's see what we can do next.
