/*
  The $tables variable holds the individual tables to be shown. A table is
  either created from a root level container or added as needed to hold root
  level forums. The following code will loop through each of the tables.
  In each table, it loops through the items in the table. These items may be
  subcontainers or forums. Subcontainers are printed simply with the name
  spanning the entire table. Forums are printed out in more detail. Subforums
  have already been attached to their parent forums in the preprocessing code
  and will display under their parents.
