The ICs for particles and the box can now be read from a (GADGET-)HDF5 file. The file name is passed to the comand line via the option -f and all the (now) unnecessary comand line options have been removed. All the values that can be read from the files are read from the file. The source file ic.c can be easily changed to read additional arrays from the HDF5 inputs. The Makefiles have been updated to reflect the changes and the need to link against the (serial) HDF5 libreary.
