Initial Release for Testing and Code Review

This release has a simple tester program to flush out the functionality of the library. It is by no means a finished product, and is intended for code review purposes only. There is an issue with memory usage that I need to revisit (the buffering of encryption/decryption data) as raised from the original work (https://github.com/kaepora/miniLock/issues/140), although I suspect JS and C# will behave very differently with regards to memory consumption.

Otherwise, I consider the basic functionality to be complete (no directory encryption yet, but that's a simple matter of including a ZIP utility, and in that case I already have one in mind).
