Replaced validation utility classes with one fatter version from my
archives. Adjusted POM to pull in required dependencies.
New utility classes:

* AutoTimeLiveCollection
	Timed collection that removes items after TTL
* TimeToLiveCollection
	A collection that removes times after TTL
* CountDownWatch
	A utility class for use as a countdown timer.
Renamed class to be more descriptive of what it is for.
All these classes were touched by the class name change.  Also added
another utility class with convenient transformation methods.
Removed bad comments from bad code merge from newer mod of older code.
