val collate : string -> string -> int

collate s1 s2 sorts string in an order that's is usaully more suited for human consumption by treating ints specificaly: (e.g. it will output: ["rfc1.txt";"rfc822.txt";"rfc2086.txt"]).

It works by splitting the strings in numerical and non numerical chunks and comparing chunks two by two from left to right (and starting on a non numerical chunks):

• Non_numerical chunks are compared using lexicographical ordering.
• Numerical chunks are compared based on the values of the represented ints and the number of trailing zeros.

It is a total order.
