See the documentaton for "reek_of".

 Notable differences to reek_of:
   1.) "reek_of" doesn't mind if there are other smells of a different type.
       "reek_only_of" will fail in that case.
   2.) "reek_only_of" doesn't support the additional smell_details hash.

 @param smell_type [Symbol, String] The "smell type" to check for.
