    MoinMoin - Hits Macro

    PURPOSE:
        This macro is used to show the cummulative hits of the wikipage where the Macro is called from.
        Optional you could count how much this page was changed. It could be used to show all page interactions too.

    CALLING SEQUENCE:
        [[Hits([all=(0,1)],[filter=(VIEWPAGE,SAVEPAGE)]]

    KEYWORD PARAMETERS:
        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.

    EXAMPLE:
       [[Hits]]

       [[Hits(all=1)]]

       [[Hits(all=1,filter=SAVEPAGE)]]

       Now we have [[Hits]] hits on this page.

       Or you can use the Frame parser to use alignment and others
       {{{#!Frame align=float:right,background=#efefef
       [[Hits]] hits
       }}}

      {{{#!Frame align=clear
      }}}
    PROCEDURE:
      It must be in "MoinMoin/macro"

      Please remove the version number from the file name!
