+=item Progess Window Handling Routines
+
+These routines handle the creation, update, increment, and closure of
+progress windows. The progress window reports to the user the number
+of items completed and an estimate of the time required to complete the rest.
+
+=over 4
+
+
+=item &Create_PrgWin
+
+Writes javascript to the client to open a progress window and returns a
+data structure used for bookkeeping.
+
+Inputs
+
+=over 4
+
+=item $r Apache request
+
+=item $title The title of the progress window
+
+=item $heading A description (usually 1 line) of the process being initiated.
+
+=item $number_to_do The total number of items being processed.
+
+=item $type Either 'popup' or 'inline' (popup is assumed if nothing is
+ specified)
+
+=item $width Specify the width in charaters of the input field.
+
+=item $formname Only useful in the inline case, if a form already exists, this needs to be used and specfiy the name of the form, otherwise the Progress line will be created in a new form of it's own
+
+=item $inputname Only useful in the inline case, if a form and an input of type text exists, use this to specify the name of the input field
+
+=back
+
+Returns a hash containing the progress state data structure.
+
+
+=item &Update_PrgWin
+
+Updates the text in the progress indicator. Does not increment the count.
+See &Increment_PrgWin.
+
+Inputs:
+
+=over 4
+
+=item $r Apache request
+
+=item $prog_state Pointer to the data structure returned by &Create_PrgWin
+
+=item $displaystring The string to write to the status indicator
