STATUS AND SCHEDULE FOR ZOOM PhysicsVectors PACKAGE

Current release:  3- and 4-vectors, including rotations and boosts on them;
		  relativistic kinematics, Rotation objects.  Partial set
		  of tutuorial examples.

Being completed:  LorentzBoost and LorentzTransformation objects.  
		  Estimated time to release -- 1 week

Will be done next:   

*  ZM_PhysVec_LinAlg.h bridging to the LinearAlgebra package.		5/15
*  "Convenience header with short syntaxes e.g. v1*R*v2			5/20
*  ZM_CLHEP_Vector.h for compatability with code using 	CLHEP HepVector 5/25
	Each class in CLHEP will be DERIVED from classes in ZMpv 
	and any extras will be provided.	
*  Completion of tutorial examples set.					5/30
*  PlaneVector class							6/5
*  Split of the .cc files into small really-basic stuff and the rest	6/15
	so that users only doing trivial things	don't pull in 
	a big object file

Tentative further intentions (subject to de-prioritizing):

	EB Vector 						(2 Weeks)
	Float4 (rather than Float8) versions 			(2 weeks)
	Version built on error-correlated numbers 		(6-9 weeks)
		(includes error-correlated numbers package)
	Affine transformations 					(1-3 weeks)
	Performance optimizations 				(2-4 weeks)

Possibilities not intended:
	Geometry3D - TangentVector, Point, Line, Plane, 	
		EuclideanTransformation, ...   			(12 weeks)
	Frobenius norms for Rotation and LT 			(1 week)
	2-Norm calculation for Rotation 			(.5 week)
	2-Norm for LorentzTransformation 			(1.5 weeks)
	Mechanisms for user to supply results if infinite
		vectors would otherwise be returned 		(2 weeks)
	Cayley-Klien parameters for rotations 			(1 week)
