6.9.2010 - Kamil Sedlak

Browse Source 
1) bug found and corrected in the field-map extrapolation of the electric 
     and magnetic fields for the spin-rotator (3DEOpera and 3D and 
     symmetryType=1 or 2). The documentation was updated.
  2) Some new variables added to the musrSimAna - the documentation has not
     been updated yet.
