What are these "improvements" and "updates"? We cannot plan without good data.

Joe Chuma commited some code cleanup and sundry unknown changes. K.O.

I removed Greg King from the MIROODAS email notification. K.O.

I commited a simplification of the Makefile:
- "make" now builds the GUI executable
- removed useless cruft for building the GUI on Solaris, RedHat 4.x, etc
K.O.

I commited a change to TTriumfFileGUI.cxx to silence the message "No Loaded
Online Histograms". K.O.

Somehow neither Joe nor myself were in the "cvs" group and could not commit
to the miroodas CVS. Fixed by editing root@dasdevpc:/etc/group + NIS reload.
K.O.

I commited fixes for a few annoying problems:
1) get rid of useless "delete/create TCanvas"
2) make the "zones" actually work
3) implement "draw in new canvas", "draw in current pad", "draw in next pad"
and "overplot in current pad"
4) consolidate all drawing into a single "DrawObject()" function.
K.O.

Modified TTriumfFileGUI to draw in the first pad when the canvas
is divided into zones.  Also, a few cosmetic changes.

Modified TTriumfFileGui.h and .cxx to fix up drop down menus, putting in
check marks to denote which option is currently in effect.  Also, a few more
cosmetic changes.

Added context menu -- single right click on a data item in the upper
TreeView window and a context menu opens on the right, choose where to plot
the item.  This becomes the default plotting location if you later double
click on an item.

Items chosen to plot from upper TreeView window will only appear once in the
lower ListView window (checks name, title, source, and type).

Also, more code clean-up (the "this" pointer was being deleted on exit even
though "this" was created on the stack and not on the heap???).

If you zoom in on the x-axis for an online histogram, the zoom now remains
in effect when the histogram is refreshed.  Also, the check mark in the
refresh drop-down menu now stays with the proper value.  Y-axis zooming is
also implemented, but commented out for now, since not sure if this is a
good idea for 1D histograms.

implemented context menu when right clicking on an online histogram in the
upper TreeView, also eliminated duplicate entries for online histograms in
the lower ListView.

The new tabbed qui has been committed to CVS.  There are still problems, and
bugs, and not all the buttons have been activated.  Work continues.

Committed MainFrame.cxx/.h with a fix for the problem of segmentation faults
while updating online histograms.  The problem was the pointers to the
histograms needed to be changed in the TGLVContainers when the histograms
were deleted and recreated due to being updated.  The main difficulty was
getting a handle on which TGLVEntry matched which histogram, when the
histogram pointers were obtained from the TPad and not the TGLVContainer. 
Anyway, you can now view online histograms without the program crashing.

The peak find panel has been added to MIDASviewer.  Click on the speed
button to open the panel.  Click the Find button to find peaks, and do a fit
if the attempt to fit check box is checked.  Fitting seems slow, but that is
all internal to ROOT.

Online histograms can now be collected in named groups.  Each group is
displayed in its own TCanvas window, instead of tabs within one window, but
hopefully that will come.  Right now, I see no way to implement TGTab's
within a TCanvas window, but the 8pi viewer does it, so it must be possible.
 A check is done so each group can contain only one instance of a histogram.

The bottom canvas window has been removed.  The superfluous buttons have
been removed.  No response, yet, to my question in the ROOT forums regarding
inserting PeakFind in the pre-defined context menu when right-clicking on a
histogram.

PeakFind has been added to the context menu when right clicking on a drawn
histogram.  There are still problems to overcome:  the PeakFind panel needs
to communicate back to the gui that it has been deleted (to overcome a
segmentation violation error when the pointer is deleted a second time);
multiple PeakFind menu items appear when the canvas is split into multiple
pads (even though it is not added if already in the menu???); still no way
found to get a context menu for the folder icons (Files, Online, Groups);
need to figure out a way to let the user choose the active pad, so he/she
can pick any drawn histogram for peak finding (currently it only works with
the latest drawn histogram).  Also, Clear All online histograms has been
added to the main menu (it used to be a button).
