title: How do I acquire the value of an observable boolean?
body: <p>I've created an 'observable' boolean variable that is to be bound (via .bind) to a UISwitch.  <br/>(The traditional imperative model would be easier; but I'm trying to learn to nuances of rxCocoa)
  <p>
  I'm not sure what to do here; I'm basing my logic on some sample code working with Strings. <br/>
  I used 'just' because I'm only interested in the one variable's toggled value.<p>
  As you can see, the closure parameter is too vague.  <br/>
  What am I missing?</p>
