docstr: Return overall distance of alignment.
  
      core logic
  
  Behaviour: returns overall distance corresponding to alignment
      not all aligners will return or implement this (optional)
  Accesses in self:
      Fitted model attributes ending in "_".
  
  Returns
  -------
  distance: float - overall distance between all elements of X passed to fit
