"crab.h" edited because:
1.) decimals were added in format of writing statistical errors to better 
    facilitate chi-sqaure fits.
2.) ERROR FIX: 3-d binning was fixed.
3.) ERROR FIX; The interactions file for pi-pi and k-k were fixed 
    (WANTI set to zero).

1.) Program prints percentage finished (10,20,30... 100) in calc.s of 
    numerator and denominator

1.) ERROR FIX: Beta version released, an error in the coulomb routines was 
    fixed that gave false answers for larger values of the relative momentum 
    when r was also large.

2.) The projections of the relative momentum for non-identical particles
    were changed, so that one could calculate k+ vs. k- correlation functions
    similarly to Lednicky. See file crab_plusminus.cpp for example, where
    this kind of binning is called.

3.) Version is renamed 3.0-beta.

1.) ERROR FIX: The Reid soft core potential for the l=1 waves was incorrectly 
    entered. Revised versions of crab_interaction_pp.cpp and 
    crab_interaction_nn.cpp were added to the distribution.

1.) ERROR FIX: The file crab_interaction_lambdap.cpp in the interactions
    directory had an incorrect mass for the lambda. Thanks to Mike Lisa for
    pointing this out.

1.) ERROR FIX: Lorentz boost was incorrect if one were doing boost along x-axis
  but was not doing longitudinally comoving boost. Thanks to Akitomo Enokizono
  for finding this.

2.) ERROR FIX: subroutine "decompose" (which was not called except for
  binnings for final printing) had qmag off by factor of 1/2 if using reduced 
  momentum. Thanks to Paul Chung for finding this.
