An improved version of the HULLAC code

Accurate and detailed atomic structure codes are needed for simulation of of spectrally resolved x-ray output of laser driven target. As such, the HULLAC code [1] has already been presented several times. Recently, cooperation was proposed to anyone interested in extending/developing the code. Until now, however, it needed to be worked on before distribution. We present here this development and the new added possibilities. HULLAC is now ready to be distributed on a basis of collaboration.
