------------------------------------------------------------------------
Yes, of course I can!
It works just like indexOfNth but starting from the end of the string.
StringUtils.lastIndexOfNth("foo,bar,baz", ",", 2); //will return 3, the second
time comma "," appears starting from the end of the string
I've used it in the tail function to determine from wich index should the
string be returned.
Maybe the method name should be changed to lastIndexOfOccurrence. Do you think
it would get easier to understand that way?
