An open source tool to convert tabulature between instruments and tunings.

This tool was originally developed to make it easier for me to play songs by the Dropkick Murphys on mandolin. Many of these songs are played on mandolin and banjo but most of the tabs online are transposed for guitar. So I decided to make something that would transpose these songs back. I realized this algorithm can also be used to transpose tabs across tunings and capos, so I added those features in as well.
