def should_not(*what, &definition)
      what << {:negative => true}
      new_assertion "should not", *what, &definition
    end
This is the negative form of #should. This is exactly like denies. Just here for syntactic sugar.

A basic eample is:

should_not("have size equal 2") { topic.size == 2 }

In addition, the #denies shortcut as available as well:

should_not(:size).equals 3

Or passing in arguments

should_not(:foo,1,2).equals(2)

@param [String,Symbol] what description or property to inspect on the topic
@return [Riot::Assertion]
