Create a combinator function named flip that takes a function as an argument and returns that function with it's arguments reversed.

For example:

flip(print)(4,5) // returns "5 -> 4"

function print(a,b) {
  return a + " -> " + b;
}

file(print)(4,5) # return '5 -> 4'

print = (a,b) ->
  a + ' -> ' + b

The idea is to reverse any number of arguments using a higher order function, without any concern for the function being passed into it.
