 This package is the core engine of Akantu. It depends on:
 \\begin{itemize}
 \\item A C++ compiler (\\href{http://gcc.gnu.org/}{GCC} >= 4, or \\href{https://software.intel.com/en-us/intel-compilers}{Intel}).
 \\item The \\href{http://www.cmake.org/}{CMake}, the cross-platform, open-source build system.
 \\item The \\href{http://www.boost.org/}{Boost} C++ portable libraries.
 \\item The \\href{http://www.zlib.net/}{zlib} compression library.
 \\end{itemize}
 
 Under Ubuntu (14.04 LTS) the installation can be performed using the commands:
 \\begin{command}
   > sudo apt-get install build-essential cmake-curses-gui libboost-dev zlib1g-dev
 \\end{command}
