Linkk's Utility Library

This one is literally all code, it's a cool library I made for myself to use in some of my Java projects, and I made it since at the time, I didn't know the full extent of the java.util library, but I guess it's better than using that stuff without knowing how it works. I'd say I did a pretty good job with most of the stuff in here, except for maybe the Trees, but overall it's a pretty good first step into data structures and other stuff!
