 """ Situate the current AdjointLayoutPlot in a LayoutPlot. The LayoutPlot specifies a layout_type into which the AdjointLayoutPlot must be embedded. This enclosing layout is guaranteed to have enough cells to display all the views. Based on this enforced layout format, a starting index supplied by LayoutPlot (indexing into a large gridspec arrangement) is updated to the appropriate embedded value. It will also return a list of gridspec indices associated with the all the required layout axes. """
