Functions

diff	Calculates the edit distance and the changeset for two given strings. The first string is assumed to be the "original", the second to be an edited version of the first. The third parameter specifies how to split the input strings, leading to a more or less exact comparison.
print_diff	Prints a colorful visual representation of the diff. This is just a convenience function for those who want quick results.
