Analysis seems to assume gfortran exists by default

The argument init_version in the init function in lattice.py is set to 0 by default. For 0 it uses code that is precompiled with gfortran and so the analysis function failed on a machine that has ifort but not gfortran. Should this variable be set to 1 by default instead? (So python will be used.) Or there could be precompiled functions for both gfortran and ifort according to whether "GNU" or "INTEL" is specified in the simulation.
