-- G4VIntersectionLocator
-  * Fix problem in ReEstimateEndPoint() behaviour for very small steps.

-  * Corrected constructor to ensure that it initialises all data members.
-  * Labelled the methods (in header) to make noticable those that 
-      must changed at every step.

+- Avoid unnecessary creation of string for debug purposes in G4PropagatorInField.

-- Fixed G4PropagatorInField.cc: 
-   * Revise condition for flagging ZeroStep to avoid fake triggering.
-     Small proposed steps (from Physics) could trigger the previous
-     simple condition for Tiny/Zero Problem steps.
-   [ This was first commited on branch geomnav-V09-02-08_branch 
-       and tagged geomnav-V09-02-80  ]

-- G4PropagatorInField: cleanup of minor methods:
-   Added new method RefreshIntersectionLocator to update the state of
-       Use this method to synchronise with IntersectionLocator.
-   Deleted long obsolete methods: SetAccuraciesWithDeltaOneStep
-           SetDeltaIntersection,  SetDeltaOneStep
-   Revised implementation to avoid using the older methods
-           GetDeltaIntersection   GetDeltaOneStep

 - Refined G4PropagatorInField.cc: 
    * Changed parameters for treating consecutive tiny/zero steps:
      - the value of default decrease factor to 0.25 (from 0.1), 
-     - the value is not used when the step size falls below a certain threshold.s
-       This threshold is changed. It is expressed as a multiple of fZeroStepThreshold 
-       instead of kCarTolerance.  The reasons are:
-         * the threshold were meant to refer to the  ZeroStepThreshold (it was kCarTolerance)
-         * the values were now much larger than this ZeroStepThreshold.
-     - The value given to the decrease factor after the first such thresholds is changed to 0.35
-       instead of 0.25, 0.5.  
+     - the value is not used when the step size falls below a certain thresholds
+       This threshold is changed. It is expressed as a multiple of fZeroStepThreshold

+       the  ZeroStepThreshold (it was kCarTolerance), and the values were now much
+       larger than 'ZeroStepThreshold'.
+     - The value given to the decrease factor after the first such thresholds is

    * Improved printing of Diagnostic message.
