docs: Add strategy parameters to candidates created by a generator.
      
      This function decorator is used to provide a means of adding strategy 
      parameters to candidates created by a generator. The generator function 
      is modifed to extend the candidate with ``len(candidate)`` strategy 
      parameters (one per candidate element). Each strategy parameter is 
      initialized to a random value in the range [0, 1]. The typical usage is 
      as follows::
      
          @strategize
          def generator_function(random, args):
              # Normal generator function
              pass
