Bug corrections:

1. Memory leak in EMfields3D.cpp has been patched.
2. Wrong 'if' tests on the constant charge boundary conditions were corrected.
3. B_ext was not applied correctly to the particle mover.
Adding a C post-processing tool. This is an 'old' tool that can be useful if you dont have python in your system.
Modifying the order of the indices when writing the fields in the parallel hdf5 file in order to read it directly in Paraview/Visit with the Xdmf format, wihtout using any postprocessing script.
Changing the Cmake configuration file to make better use of the options. Currently there are two options: parallel HDF5 and coupling with BATS-R-US.

Add -DIPIC_PARALLEL_HDF5=ON to compile the code with parallel HDF5.
Add -DIPIC_BATSRUS=ON to compile with the coupling options.

Alternativelly use 'ccmake' or 'cmake -i', the two options are available in the GUI.
