This Github contains some utility libraries that I have found personally useful. The quality of the code varies by how much I've used it, from quite good in the cases I've applied it to, to, "I think it should work." So, no guarantees are made of the fitness of this code for any purpose. If you notify me of a bug, I'll try to fix it if I have time (depending on the complexity of the bug/fix).
At any rate, I hope you find this code useful, too.
