// Possible options:
// id - specifies the groupItem's id; otherwise automatically generated
2010-06-11 15:08:14 -07:00
// userSize - see <Item.userSize>; default is null
// bounds - a <Rect>; otherwise based on the locations of the provided elements
// container - a DOM element to use as the container for this groupItem; otherwise will create
// title - the title for the groupItem; otherwise blank
// focusTitle - focus the title's input field after creation
// dontPush - true if this groupItem shouldn't push away or snap on creation; default is false
