I have to write the following functions using SML.  Write a function concat_with that takes a separator string and a list of strings, and returns the string that consists of all the strings in the list concatenated together, separated by the separator. The separator should be only between elements, not at the beginning or end. Use ML's - operator for concatenation (e.g., "hello" - "world" evaluates to "helloworld"). Sample solution is 5 lines.
