MSGLOG

Graphical display of all messages from within a macro

MSGLOG creates a window in which text messages are displayed.  Typically it
is used to display informational, warning, or error messages from a macro.
The message display includes message type, date/time and message text
color-coded by severity:  green for informational messages, yellow for
warning messages, and red for error messages.

MSGLOG set the Midas.logger field to get a copy of all messages generated
in the macros Midas context.

To handle logging to a file, see the REPORT intrinsic.

To automatically instantiate this in a NeXtMidas macro with a panel, use
  PANEL/LOGGER
This adds the logger to the bottom fixed region of the panel.
