Sends a get request for the supplied list of ObjectId or VarBind
 objects.

 Returns a list of the varbind values only, not the entire response,
 in the same order as the initial object_list.  This method is
 useful for retrieving scalar values.

 For example:

   SNMP::Manager.open(:host => "localhost") do |manager|
     puts manager.get_value("sysDescr.0")
   end
