[Click] nsclick - interfacing with ns2

[Michael Neufeld]

Yup -- Kendy Kutzner added nsclick support a while back for calling 
Click element read and write handlers from TCL, I guess it must not have 
made it into the documentation. Here's a code snippet which initializes 
some Click element parameters at the start of simulation:

       # Tell the antenna control to go into "receive" mode
       $ns_ at 0 "[$node_($i) set classifier_] writehandler 
\"antennactl\" \"mode\" \"receive\""
       # Set parameters for idle naash thing
       $ns_ at 0 "[$node_($i) set classifier_] writehandler 
\"antennactl\" \"unrelatedtrafficmax\" \"$naashunrelatedsaturate\""
       $ns_ at 0 "[$node_($i) set classifier_] writehandler 
\"antennactl\" \"unrelatedtrafficupsub\" \"$naashunrelatedupsub\""
       $ns_ at 0 "[$node_($i) set classifier_] writehandler 
\"antennactl\" \"unrelatedtrafficdownsub\" \"$naashunrelateddownsub\""


Basic calling scheme is:

writehandler "elementname" "handlername" "value"
