Bass clarinet fingering chart

[Mike Solomon]

Hey lilypond-users,
    Before I put this on the LSR, please play around with this.
Specifically, please

1) Make it less sprawling.
2) Find anything that's broken (the below examples work).
3) Change layout to better-suit your wind-playing needs.
4) Make any and all layout or coding suggestions.

THANK YOU!!!
~Mike
