mingus.extra.StringTuning should be more robust

[GoogleCodeExporter]

What steps will reproduce the problem?
from mingus.extra import tunings; from mingus.containers import 
NoteContainer
tuning = tunings.get_tuning("Guitar", "standard", 6, 1)
print "\n".join(repr(chord) for chord in 
tuning.find_chord_fingering(NoteContainer().from_chord("Am"))

What is the expected output? What do you see instead?
I expect to be able to choose the maximum amount of fingers to use in 
find_chord_fingering, as a positional or keyword argument, whose value 
defaults at 4. For example, the fingering [0, 0, 0, 0, 0, 0] uses 0 
fingers, while [0, 2, 2, 1, 0, 0] requires 3. Some fingerings in the output 
require 6 fingers, like [17, 15, 14, 17, 17, 17], which is impossible to 
play with one hand.

What version of the product are you using? On what operating system?
I am using mingus 0.4.2.3 on Ubuntu 10.04 Alpha 3.

Please provide any additional information below.
Attached is fingers.py which includes fingers(), which will determine the 
number of fingers a fingering requires. I would recommend adding the 
utility function distance() that will return the distance of a fingering, 
related to max_distance in find_chord_fingering().
