Create and activate figures by name

Finds and activates, or creates, figure with user-specified name.

If no name is provided, creates figure named "untitledn" (where n is incremented to result in a unique name).

SYNTAX:
togglefig('My Figure');
If figure named 'My Figure' exists, it will be activated (brought to the front and shown). Otherwise, it will be created.

h = togglefig('My Figure');
Also returns the handle to the specified or created figure.

togglefig;
Creates and activates new figure named untitled1, untitled2, ...
Note: You can subsequently activate these figures with, for instance, togglefig('untitled1').

OTHER EXAMPLES:
NOTE: This example requires the Image Processing Toolbox
im = imread('cameraman.tif');
for ii = 1:10
thresh = ii/20;
togglefig('Threshold');
imshow(im2bw(im,thresh));
title(sprintf('Threshold = %0.2f',thresh));
pause(1)
end
Motivation:
I've found this to be exceptionally useful in algorith-development
mode, particularly when iterating on cells in the cell-mode editor. (I
use this function in almost every mfile I write these days.)
