calculate the similarity of two strings
The "String::Similarity" calculates the similarity index of its two
arguments. A value of '0' means that the strings are entirely
different. A value of '1' means that the strings are identical.
Everything else lies between 0 and 1 and describes the amount of
similarity between the strings.
