docs: Combine a Query with an AND operator between it and
  the current Query object.
  
  Example:
  var isAged  = new StackMob.Collection.Query().equals("age", "25");
  var isNYC   = new StackMob.Collection.Query().equals("location", "NYC");
  var notJohn = new StackMob.Collection.Query().notEquals("name", "john");
  var notMary = new StackMob.Collection.Query().equals("location", "SF").notEquals("name", "mary");
  var isLA    = new StackMob.Collection.Query().equals("location", "LA");
  
  isAged.and( notJohn.or(notMary).or(isLA) );
  
  @param  {StackMob.Collection.Query} b - A query object to OR with this object
  @return {StackMob.Collection.Query} A new query equivalent to A AND B, where A is the object this method is called on and B is the parameter.
