# handle_response is the callback that is 
# invoked to print out the data returned by
# the plugin.
# 
# Format of the response hash:
#  {data => [ 'data str1', 'data str2', '...' ] }
#
#    Results are printed as:
#       data str1
#       data str2
#
# or:
#  {data => [ {desc => [ 'desc1' ],
#              contents => [ 'contents1' ] },

#              contents => [ 'contents2' ] } 
#                :
#            ] }
#    NOTE:  In this format, only the data array can have more than one 
#           element. All other arrays are assumed to be a single element.
#    Results are printed as:
#       desc1: contents1
#       desc2: contents2
#
# or:
#  {node => [ {name => ['node1'],
#              data => [ {desc => [ 'node1 desc' ],
#                         contents => [ 'node1 contents' ] } ] },
