Not yet in operation and some of the headerfiles need to be
cleaned up. Need to remove physics.h.

At the moment the matched distribution generator is not enabled! 

Brought back saving in local frame for cyclotron tracker. Reverted the way mean E is calculated in PartBunch. Hopefully, restarts in local as well as in global frame now work in the cyclotron tracker.

- moving the following classes over from OPAL to CLASSIC
  o OpalField       -> ClassicField
  o OpalRing        -> Ring
  o OpalRingSection -> RingSection
  o LossDataSink
- clean up
- splitting Options into classic and opal options

- putting own header file first
  o for reason see http://www.cplusplus.com/forum/articles/10627/#msg49679 and
                   http://www.cplusplus.com/forum/articles/10627/#msg49680

1. Changed the way eKin_m is calculated in PartBunch to be consistent between P and E especially when restarting, 2. Removed some debug outputs.

Cosmetics, Typo, and an indexing error in Distribution.cpp that lead to (n_processors - 1) extra particles

Major Changes: 1. No more dumping or restarting in LOCAL frame. 2. OPAL-CYCL now recalculates reference* variables before dump and saves in H5 file. 3. OPAL correctly reads reference* values and calculates beta*gamma correctly from Ekin (was factor 1000 wrong before) Note: Transformation of bunch data into local frame must now be done in POSTPROCESSING -> upgrade H5root

No commit message

Changed ConvertBetaGammaToeV and ConverteVToBetaGamma such that negative values can be converted -DW

The GAUSS distribution is now using a Choleski decomposition 
to correlate. One can use either
CORRX,CORRY, CORRZ,R16,R26, R36, R46
or the correlation matrix R a la TRANSPORT.
