------------------------------
G4Transportation modified to use new FieldTrack, and get Kinetic Energy from it.
G4Transportation.cc: Set the True Step Length in G4Transportation.cc
This new FieldTrack together with changes in associated Equation of Motion
classes implement the momentum vector as independent variable in place of the
velocity.
(Cosmetic: updated other files to the head - as there were no differences from it.)
So this tag requires
- new geometry/magneticfield tag "field-V03-00-01", and
- new geometry/volumes tag "geomvol-V03-00-03" for new G4PropagatorInField ().

Feb 27, 2001 J. Apostolakis (transport-V03-00-00)
------------------------------
- G4Transportation.cc:
* Modified calculation of energy at the end of field step
to make it more accurate at low velocities,
(while remaining correct at high gammas).
G4Transportation.cc: Set the material in materialChange, in order to get correct
behaviour for volumes that parameterise the material.
(Fix is dependant on changes to particleChangeForTransport and StepPoint)
This improves the energy determination.
Together with electromagnetic/standard tag "stand-V03-00-03"
this addresses the main problem in propagating in an electric field
(Problem report # 108 )
Modified setting of touchable change, in order to preserve const-ness where it exists.
Sep 22, 2000 V. Grichine (transport-V02-00-00) [recorded by G.Cosmo]
---------------------------
- G4Transportation.cc:
o added formula for Tkin corresponding directly to
relativistic definition of Tkin = Etot - mc^2 = mc^2(gamma -1),
where gamma is a particle Lorentz factor.
o general cosmetics.

charged particles.

The Velocity Vector for Transport in a magnetic field is now set correctly.
--> previously the scalar velocity was automatically promoted to a 3-vector

Fixes:
Nov 19, 1998 J. Apostolakis (transport-00-03-04)
------------------------------
- Fixes:
1) The final energy is set equal to the initial energy, because
the PropagatorInField does not calculate it correctly yet. NEEDS Fix
2) If the requested step size is zero and safety is zero, the
step is now considered geometry limited. (This can happen
if a discrete process tries to take a step that is very small
compared to the mean free path.) Problem observed by Laszlo in EM tests.
3) PostStepGetInteractionLength now returns DBL_MAX, not kInfinity.
Nov 11, 1998 J. Apostolakis (transport-00-03-03)
------------------------------
- Changes to accomodate new interface of Field:
G4PropagatorInField and G4FieldTrack.

geometry limited the step was not set.

Checks whether the particle is out of the world volume
If so it has exited and must be killed.

The boolean flags for touchables are now initialised. & Other small fixes ?
Test code for non-relocating case added (for debugging).

June 08, 1998 J. Apostolakis (trans-06-04)
Corrected Safety computation for the case of the field (adding endpoint
distance instead of curve length.)
Added PostStepDoIt method that tries to relocate the particle using
G4ParticleChangeForTransport
Transportation is no longer a G4ContinuousProcess.

Modified it to recomputate Safety at the start of a step. To do this
it uses the previous step's calculated safety and endpoint.

June 08, 1998 J. Apostolakis (trans-06-02)
Modified it to add re-computation of Safety at the endpoint of a step,
when the safety would become negative. This is done to allow processes
to benefit from a realistic (geometrical) value of the safety. The
request to do this was from EM physics

June 03, 1998 J. Apostolakis (trans-06-01)
------------------------------
- The safety we is now generalised to mean the limit of assumption of all
processes. The AlongStepGPIL input value is not the remainder from the
previous step's geometrical safety.
So the transportation must recalculate the starting point's safety here.
As a zeroeth order approximation we set it to zero.

------------------------
- A new process, G4UserSpecialCuts, was added to allow the
user an alternative method to set some user cuts.

---------------------------
- The transportation does the absolute minimum required to conform to
the new scheme for ParticleChange: G4VParticleChange is used in signature.
[ But default G4ParticleChange is still used ].
