Anglo Concertina C/G Tablature

This plugin adds Anglo concertina tablature (fingering) diagrams for various layouts: Wheatstone, Jeffries and my instrument layout - it was supposed to be a Jeffries, but in fact it's a unique mix of those two. If your layout is different than these three published here, you should modify the buttonPush and buttonPull arrays in the plugin source code and set the correct key positions for accidentals.

The key naming is as follows:
1-5 - C Row, left hand
6-10 - G row, left hand
1a-5a - accidentals, left hand
1.-5. - C Row, right hand
6.-10. - G row, right hand
1b-5b - right hand accidentals
No underscore - push; Underscore - pull
