## Create a uitoggletool object and return a handle to it.
##
## uitoggletool are togglebuttons that appear on a figure toolbar.  The
## button is created with a border that is shown when the user hovers over
## the button.  An image can be set using the cdata property.
##
## If @var{parent} is omitted then a uitoggletool for the current figure is
## created.  If no figure is available, a new figure is created first.  If a
## figure is available, but does not contain a uitoolbar, a uitoolbar will be
## created.
##
## If @var{parent} is given then a uitoggletool is created on the
## @var{parent} uitoolbar.
##
## Any provided property value pairs will override the default values of the
## created uitoggletool object.
##
## Uitoggletool properties are documented at @ref{Uitoggletool Properties}.
##
## Examples:
##
## @example
## @group
## % create figure without a default toolbar
## f = figure ("toolbar", "none");
## % create empty toolbar
## t = uitoolbar (f);
## % create a 19x19x3 black square
## img=zeros(19,19,3);
## % add uitoggletool button to toolbar
## b = uitoggletool (t, "cdata", img);
## @end group
