Nite Flite Script Library 1.21

Nite Flite Script Library is a collection of script libraries that implement the basic computer science structures (stacks, queues, priority queues), file operations (read, write, and append), and sorting (Bubble sort, Insertion sort, Merge sort, and Quick sort).
Nite Flite Script Library is a set of routines that can be used and reused in lots of ways. At the same time, these libraries also help new scripters to understand the basics of programming.
The routines in this collection, while by no means "the final word" on the subject, have been written with an eye toward helping scripters to write better code that is both fast and clean.
Enhancements:
- The priority queue library was incorrectly handling inserts in the middle of the queue. This has been corrected.
- The stack library has had a peek handler added so that you dont have to pop an item to see what it is.
- The miscellaneous library has had a handler added to swap/replace text in a given string with other text.
- Fixed a bug that caused non-existent items to be referenced when inserting items whose priority was equal to the first and last items in the queue.
