                   9465: Handles the viewing of grades.
                   9466: 
                   9467: This is part of the LearningOnline Network with CAPA project

                   9471: 
                   9472: Do an ssi with retries:
                   9473: While I'd love to factor out this with the vesrion in lonprintout,
                   9474: that would either require a data coupling between modules, which I refuse to perpetuate (there's quite enough of that already), or would require the invention of another infrastructure
                   9475: I'm not quite ready to invent (e.g. an ssi_with_retry object).
                   9476: 
                   9477: At least the logic that drives this has been pulled out into loncommon.
                   9478: 
                   9479: 
                   9480: 
                   9481: ssi_with_retries - Does the server side include of a resource.
                   9482:                      if the ssi call returns an error we'll retry it up to
                   9483:                      the number of times requested by the caller.
                   9484:                      If we still have a proble, no text is appended to the
                   9485:                      output and we set some global variables.
                   9486:                      to indicate to the caller an SSI error occurred.  
                   9487:                      All of this is supposed to deal with the issues described
                   9488:                      in LonCAPA BZ 5631 see:
                   9489:                      http://bugs.lon-capa.org/show_bug.cgi?id=5631
                   9490:                      by informing the user that this happened.
                   9491: 
                   9492: Parameters:
                   9493:   resource   - The resource to include.  This is passed directly, without
                   9494:                interpretation to lonnet::ssi.
                   9495:   form       - The form hash parameters that guide the interpretation of the resource
                   9496:                
                   9497:   retries    - Number of retries allowed before giving up completely.
                   9498: Returns:
                   9499:   On success, returns the rendered resource identified by the resource parameter.
                   9500: Side Effects:
                   9501:   The following global variables can be set:
                   9502:    ssi_error                - If an unrecoverable error occurred this becomes true.
                   9503:                               It is up to the caller to initialize this to false
                   9504:                               if desired.
                   9505:    ssi_error_resource  - If an unrecoverable error occurred, this is the value
