	Optional you could count how much a page was altered on this or all pages.

    CALLING SEQUENCE:
        [[Hits([text],[bgcolor=bgcolor],[all=(0,1)],[filter=(VIEWPAGE,SAVEPAGE)],[divid=(logo,searchform)],[noframe=(0,1)])]]

    OPTIONAL INPUTS:
        text: the text which is used as description of counter number

    KEYWORD PARAMETERS:
        bgcolor: if set to the rgb color triple this color is used. Default color is #FFFFFF
	all: if set to 1 then cummulative hits over all wiki pages is returned. Default is 0
	filter: if set to SAVEPAGE then the saved pages are counted. Default is VIEWPAGE.
	divid: if set this divid is used. Default is logo. You could use each defined in screen.css.
	       I have tried logo and searchform.
	noframe: if set to 1 only text is written without a table border. Default is 0.

    EXAMPLE:
      [[Hits]]

      [[Hits(counts)]]

      [[Hits(counts,divid=searchform)]]
