[C150_I] Work in progress commit for stashing history of Func<T> experimentation.

- The Func calls could've made the code cleaner, however they did dramatically
  affect performance on the longer strings. Apparently they were called enough
  times in all the recursive functions that the extra milliseconds they took to
  call actually added up to significant figures, e.g. a 50% processing duration
  increase on the "babies" string!
