    PetscViewerSAWsOpen - Opens an SAWs memory snooper PetscViewer.

    Collective on MPI_Comm

    Input Parameters:
.   comm - the MPI communicator

    Output Parameter:
.   lab - the PetscViewer

    Options Database Keys:
+   -ams_port <port number> - port number where you are running SAWs client
.   -xxx_view ams - publish the object xxx
-   -xxx_saws_block - blocks the program at the end of a critical point (for KSP and SNES it is the end of a solve) until
                    the user unblocks the the problem with an external tool that access the object with the AMS

    Level: advanced

    Fortran Note:
    This routine is not supported in Fortran.


    Notes:
    Unlike other viewers that only access the object being viewed on the call to XXXView(object,viewer) the SAWs viewer allows
    one to view the object asynchronously as the program continues to run. One can remove SAWs access to the object with a call to
    PetscObjectSAWsViewOff().

    Information about the SAWs is available via http://www.mcs.anl.gov/SAWs.
