Obtain feedback from Molinillo and crystal-molinillo projects

[baron1405]

I have created a Java port of the Molinillo dependency resolution algorithm. This is motivated by an investigation into dependency management algorithms and implementations for a potential Java build tool project. The port attempts to remain as true as possible to the original Ruby project. In addition, I have included the CocoaPods/Molinillo#153 and CocoaPods/Molinillo#158 PRs. All test cases from the Molinillo project are included and pass. I would greatly appreciate any feedback from @segiddins, @greysteil, @waj, and anyone else familiar with the algorithm. A big thank you to the Molinillo and crystal-molinillo projects for their great work!

Nice! I'll leave review to someone else - it's been a few years since I thought about dependency resolution now, but the ping put a 😄 on my face!
