docs: The `count` method works mostly like the `live` method, but no events are
  bound, the functionality is only executed once.
  
  @param   {Nodes|String}  targets   All elements that should be counted.
  
  @param   {Function}      callback   The callback to fire whenever the
  element's value changes. The callback
  is called with the relevant element
  bound to `this` and the counted values
  as the single parameter.
  
  @param   {Object}        [options]  An object to modify Countable's
  behaviour.
  
  @return  {Object}    Returns the Countable object to allow for chaining.
