title: Drools rule: Checking if a String contains any String in a collection
body: <p>Is there a way in drools to check if a string input contains any of the following Strings in a collection?</p>
  
  <p>For example: 
  String input="How now brown cow."
  List stringList=[blue, brown, green, orange]</p>
  
  <p>I want to be able to say:
  If input.contains(any String in stringList)...</p>
  
  <p>Thanks!</p>
