Merge pull request #48 from dfaligertwood/patch-1

Partial rewrite of includePattern function
re-add git-commands to the "old" master branch

This is to be able to include the command in the "Trunknes Lied"
project.
git-command: Uncomment  oll-base reference

THis is due to the "revert" of that snippet to the
old structure.
move index higher in README.md

For people who have just discovered this repository, learning how to
use it or contribute to it is irrelevant until they first establish
that they are somehow interested in the contents.  So move the index
to appear before the "Using this repository" or "Contributing"
sections.

Additionally, rename the index from "Snippet categories" to
"Contents", since not all items are snippets.

divisi: add code by David Kastrup
Initial version of divisi/partcombine framework
ensure synchronization when input lengths don't match
use \removeWithTag instead of \keepWithTag.

That method will at least preserve music that the user has tagged
for some other purpose, and it co-exists with \removeWithTag for other
purposes.

Just in case anyone uses the \divisibleStaff with his own tags, and might
not think to include 'together in \keepWithTag score \divisibleStaff ... ,
I added a function to clean up the divI/divII/together tags when we are
done with them.

Installation script for Abraham's fonts (WIP)

This is an initial version of a script that simplifies
the installation of alternative fonts with the help of
symlinks.

Probably it doesn't work on Windows, and Mac support hasn't
been implemented yet. Also it wouldn't work on installations
through a Linux package manager.

The missing implementations should be easily done, but
not by me ...
