MYWAITBAR: Display multi functional animated wait/progress bar

See a preview on "http://i.imgur.com/QdHB3Id.gif"
H = MYWAITBAR(X,'Title','message',CircularScroll);
creates and displays a waitbar of fractional length X, a Title and a
message. It adds the option to make an indeterminate time waitbar
through the option CircularScroll (true or false).
The handle to the waitbar figure is returned in H.

MYWAITBAR(X,H) will set the length of the bar in waitbar H (already
created) to the fractional length X.

MYWAITBAR(X,H,'message') will update the message text in
the waitbar figure, in addition to setting the fractional
length to X.

MYWAITBAR(X,H,'message','title') will update the title in
the waitbar figure, in addition to setting the fractional
length to X and the message text to 'message'

MYWAITBAR('CircScroll',H) makes the waitbar with undefined value,
scrolling contiuously.

MYWAITBAR('CircScroll',H,'message') makes the waitbar with undefined
value, scrolling contiuously with a custom message.

MYWAITBAR('CircScroll',H,'message','title') makes the waitbar with
undefined value, scrolling contiuously with a custom message and title.

This waitbar can be used in a for loop or before an operation whose
duration cannot be predicted

Example:
h = mywaitbar(0,'Please wait...','Computing...',true);
pause(3);
for i=1:300,
% computation here %
pause(0.01);
mywaitbar(i/300,h,[num2str(i) '/300'],sprintf('Running (%.0f%%)',i/300*100));
end
mywaitbar(i/300,h,[num2str(i) '/300'],'Finished');
pause(1);
mywaitbar('circscroll',h,'Last operations...');
pause(2);
close(h);

Properties can be also accessed through the figure handle.
