% Usage:
% - define and index item with \indexItem $sortstring $markup
% - use \indexSection $sortstring $markup to divide the index into several sections
% - display the alphabetical index with \markuplines \index
% code ist mostly taken from ./ly/toc-init.ly and just renamed and slightly modfied
%% defined later, in a closure
