   * MElectron.cc:
     - changed upper limit in InteractionLength from 1e-11 to 2e-11
     - changed upper limit of p_e in EnergyLoss from -10.8 to -10.6

   * MParticle.[h,cc]:
     - replaced Planck by tanjas background
     
   * background.txt:
     - added

   * MPhoton.[h,cc]:
     - changed lower limit of Int2-Integration for Interaction Length
       in case Eg<5e4 to fit better its needs
     - changed max/min of drawing interaction length
     - changed lower limit of interaction length plot

   * analp.C:
     - added plotting 1h1426 data
     - changed alpha/plot from -2/2 to -1/1 (which means I do the well
       known E^2 plot of an E^-2 spectrum)
     - added a cutoff to simulate cutoff spectra
     - some small corrections for the layout of the plots

   * phys.C:
     - added a maximum number of inv. Compton processes
     - don't throw away photons which were reemitted lower than the lower
       limit of the plot (so they are still written to the file)
     - changed the lower limit of the PhotonSpect simulation function
       to a physically more realistic value. No photon which don't have
       an corresponding angle are produced anymore.
     - stop the electron only if its energy is less than a thousand
       of its primary energy
