##
## Create a uipanel object.
##
## uipanels are used as containers to group other uicontrol objects.
##
## If @var{parent} is omitted then a uipanel for the current figure is
## created.  If no figure is available, a new figure is created first.
##
## If @var{parent} is given then a uipanel relative to @var{parent} is created.
##
## Any provided property value pairs will override the default values of the
## created uipanel object.
##
## The full list of properties is documented at @ref{Uipanel Properties}.
##
## The optional return value @var{hui} is a graphics handle to the created
## uipanel object.
##
## Examples:
##
## @example
## @group
## ## create figure and panel on it
## f = figure;
## p = uipanel ("title", "Panel Title", "position", [.25 .25 .5 .5]);
##
## ## add two buttons to the panel
## b1 = uicontrol ("parent", p, "string", "A Button", ...
##                 "position", [18 10 150 36]);
## b2 = uicontrol ("parent", p, "string", "Another Button", ...
##                 "position",[18 60 150 36]);
