The WonderlandStyle class implements different animation styles. The four styles this class provides are gently (slow-in, slow-out), beginGently (slow-in), endGently (slow-out), and abruptly (linear).

Animations use these styles through blocks of the form:

[ :elapsed :duration | WonderlandStyle beginGentlyAfter: elapsed outOf: duration ]

The intention is that using this mechanism the user can specify arbitrary styles using blocks and pass them to animations.

	abruptlyAfter:outOf: Returns the proportion done for an Abrupt animation style after elapsed seconds (out of duration seconds) have elapsed.
	beginGentlyAfter:outOf: Returns the proportion done for an animation using the BeginGently style after elapsed seconds (out of duration seconds).
	endGentlyAfter:outOf: Returns the proportion done for an animation using the EndGently style after elapsed seconds (out of duration seconds).
	gentlyAfter:outOf: Returns the proportion done for an animation using the Gently style after elapsed seconds (out of duration seconds).
	oneAfter:outOf: Returns the proportion of Animation done using an instantaneous style - this is also 1.0.

	new Users shouldn't create any instances of this class, so this method throws an error if they try.

	private	top
	gently:lowerBound:upperBound: This method converts a linear proportion done to a slow in - slow out proportion. If x is less than A then the animation is in the slow in part, while if x is greater than B then the animation is in the slow out part.
