docs: Selects the best matching formatter for the provided type and width from this configuration.<p>
  
  This method first tries to find the formatter for the provided container type.
  If this fails, it returns the width based formatter that matched the container width.<p>
  
  @param containerTypes the container types (comma separated)
  @param containerWidth the container width
  
  @return the matching formatter, or <code>null</code> if none was found
