Determine the optimal way to play a given chord sequence

[noeddl]

The idea is that the user inputs a sequence of chord names and is presented a diagram showing the most convenient way to play these chords. I'm not sure how (and if at all) this can be computed reliably but it will probably involve some kind of distance measure between different chord shapes.

For this, the compact representation described in #16 would probably be helpful ad easier to read.

Something similar could also be useful for melodies.

In this project, the distance between different chord fingerings is calculated and compared using a modified Levenshtein distance:
