Lambda polarization studies --> removed pseduorapity cuts to avoid a deformation of the angular distribution used to extract the polarization

For transverse lambda polarization studies it is necessary to remove the cuts in pseudorapity present in the dec file minbias=BiasedLambdaPt300MeV. These cuts interfere with the distribution of the cosine of the angle between the decaying proton and the normal to the Lambda production plane (cos\theta). In generation this distribution should be flat, while with eta cuts a v shape is obtained. New dec file with no eta cuts minbias=BiasedLambdaPt300MeVNoEtaCut already checked and a flat cos\theta distribution is obtained, as expected
