-- Requests treeview contents from browser that matches pm_entry's text.
-- This function is called internally and shouldn't be called by a script.
-- @param full_path A numerically indexed table of treeview item parents. The
-- first index contains the text of pm_entry. Subsequent indexes contain the
-- ID's of parents of the child requested for expanding (if any).
-- @param expanding Optional flag indicating if the contents of a parent are
-- being requested. Defaults to false.
-- @return table of tables to for display in the treeview (single level).
-- Each key in the return table is the treeview item's ID. The table value
-- has the following recognized fields:
-- parent - boolean value indicating if this entry can contain children. If
-- true, an expanding arrow is displayed next to the entry.
-- pixbuf - a string representing a GTK stock-id whose icon is displayed
-- next to an entry.
-- text - the entry's Pango marked-up display text.
-- Note that only a SINGLE level of data needs to be returned. When parents
-- are expanded, this function is called again to get that level of data.
