Rough draft of Task subsystem
Shutdown handler implemented and integrated. 
Pretty neat, I'm happy with it
Refactoring. Changed package structure and class locations.
Shutdown system
Added blocking behavior, changed so it would attempt to execute as many
hooks as possible.
Command subsystem
-Partial progress. Wanted to commit at least partway through, since 
it's such a large amount of code. Essentially, the structure and logic 
flow is laid out. Implementation details are needed.
Command System
Additions and refinements to the class structure and logic flow.
Command system
Implemented logic up to executing a command with no parameters
(Parameters are not being parsed, yet)
Command System
Implemented optional parameter parsing
Command System
Implemented required parameters. Tied in the CommandService to the 
console so commands can be executed from the console
Command System
Javadoc documentation. Wow, doing this after-the-fact is terrible!
Shutdown system
Added hook for TaskEngine
Tweaked behavior of CommandService so that it stops on its own
Added shutdown command
IO Refactoring
Going to make an effort to consistently just use PrintWriter and 
BufferedReader
Task Engine
Refined class structure, added Cancellable and Counted tasks.
