Implemented ScoreManagerConfiguration._path_to_storehouse_annotation(path).

Examples:

    >>> configuration = scoremanager.core.ScoreManagerConfiguration()

    >>> path = '/Users/trevorbaca/Documents/abjad/abjad/stylesheets'
    >>> configuration._path_to_storehouse_annotation(path)
    'Abjad'

    >>> path = '/Users/trevorbaca/Documents/abjad/scoremanager/materials'
    >>> configuration._path_to_storehouse_annotation(path)
    'Abjad'

    >>> path = '/Users/trevorbaca/Documents/baca/score_manager_library'
    >>> configuration._path_to_storehouse_annotation(path)
    'Bača'

    >>> path = '/Users/trevorbaca/Documents/scores/traiettorie'
    >>> configuration._path_to_storehouse_annotation(path)
    'Traiettorie inargentate'

The method returns a string.

The string describes where the path resides:
    * somewhere in the Abajd library
    * somewhere in the user library
    * in a score

Method will be used to annotate menu titles and menu entries.
