UTiL 
A collection of utility libraries for Appcelerator's Titanium and it's Alloy MVC framework. The app contains samples and tests for some of the libraries.
This is a public, but personal library. It may change at any time without notice! Feel free to fork and contribute, but I'll decide what PR's to accept based on their potential use for my own projects.
