1. The method by which Bext is included in the code has changed for the Dipole case. Bext is added in PIdot MUdot and sustensor for the fields and also in the mover. A fetch factor, Fext, has been included to apply Bext during time and avoid instabilities of the code at the initialization of the simulation.

2. J, E, rho, B, and B_tot are given in the output file. B_tot contains B + Fext*Bext. In the future we will add options in the input file to select the fields that must be saved. The minimum should be E and rho. Other quantities can be derived from these two fields. In the future B should be saved and retreived from the cells and not from the nodes.

3. Reading particles in parallel. In large computers the lecture of particles was not working. The particle file is now read in parallel by each processor, minimizing the use of memory. Each processor sorts the particles and distribute them to the corresponding processor. The new code is implemented using Parallel HDF5 only. In the future all IO will be moved from H5hut to Parallel HDF5.
