  • added "find" method to "Tags" class to locate "Tag" object that matches the string
  • fixed "getitem" and "setitem" methods of the "Tags" class
  • added "GridSearch" meta-classifier with convenience properties to module "weka.classifiers"
  • added "SetupGenerator" and various parameter classes to "weka.core.classes"
  • added "MultiSearch" meta-classifier with convenience properties to module "weka.classifiers"
  • added "quote"/"unquote" and "backquote"/"unbackquote" methods to "weka.core.classes" module
  • added "main" method to "weka.core.classes" for operations on options: join, split, code
