Find substrings occurring in n input strings?

[william-gosimplr]

Thanks for writing this implementation.

I would like to add a method which takes an integer n and outputs a list of substrings which occur in at least n of the strings passed to add_string().

What do you see as the best way of going about this?

Thanks.

Hi!

Sorry for getting back to you this late. I have reworked the whole thing and the next thing on my todo list is the longest common substring algorithm. Your algorithm is just a slight variation of this one so once I get the vanilla one working, yours should not be too much work to devise!
