title: UI for creating business rules in NRules
body: <p>I have been searching for a rules engine to be used in a data import system i am creating.</p>
  
  <p>I found several rules engines but it looks like NRules is the most popular also i found CodeEffects which is good but not free. </p>
  
  <p>So i was wondering if there is a friendly UI to let the end-users create the rules with NRules just like CodeEffects <a href="http://codeeffects.com/Business-Rule-Demo" rel="nofollow noreferrer">demo</a>.</p>
  
  <p>Appreciate your help.</p>
