org.apache.maven.werkz.Goal
Abstract Goal to attain.
A Goal embodies both an action and the precursors for that action. A Goal's precursors will be satisfied before attempting to perform the target Goal's action. There may be a case that once precursors have been satisfied there is no further action required to be perform for a particular Goal.

A Goal's postcursors are also tracked so that if a Goal's state has been changed and the Goals ahead of it in the hierarchy need to be notified, it can percolate forward and have it's postcursors satisfied.
