Permutations of a string
#!/usr/bin/env ruby
# Recursive method, print all strings permutations with length = str.length.
# Iterrate over each character of given string and recursively call
# string_permutations. Each time, a letter from str is stripped and added to elmt.
# When str.length reaches zero, print elmt.
def string_permutations(str, elmt='')
