Description
I would like to be able to visualize only one instrument at a time. For instance, I only want to see the tabs for the lead guitar, but listen to all instruments. I was able to do this by creating a filter. But there should be built in filters for every specific instrument/name.

After the first code section, there should be some info about how installing Gwion.

Well that's basically make install, but it should ensure that libraires (ast and util) are also installed (make install-all?).

Uninstallation should not remove library files, unless requested (make uninstall-all?)
