Dictation container base class

This class is used to store the recognized results of dictation elements 
within voice-commands.  It offers access to both the raw spoken-form words 
and be formatted written-form text.

The formatted text can be retrieved using
:meth:`~DictationContainerBase.format` or simply by  calling ``str(...)``
on a dictation container object. A tuple of the raw  spoken words can be
retrieved using :attr:`~DictationContainerBase.words`.
