New features, the paper has been accepted to MNRAS

New features:

• You can configure Freddi from configuration file freddi.ini instead of command line.
• Output data file mirrors configuration in the header. You can just copy-past this header to freddi.ini, uncomment it and obtain the same results.
• New option --lambda. You can specify numerical optical wavelengths in Angstrom and obtain spectral flux for the corresponding photon frequency.
• New initial condition options have been added:
  • --gaussF for Gauss distribution of viscous torque. --gaussmu and --gausssigma specifies parameters of this distribution.
  • --Mdot0 specifies initial accretion rate for several initial conditions.
  • --Mdisk0 specifies initial disk mass.
• Readme has been updated.
• Some default parameters have been changed.
• Numerical bugs have been fixed, e.g. the first data line in freddi.dat corresponds to initial condition now, not to the time moment just after it.
