Oleg E. Peil 911f127789 Ported C-style 'dos_tetra' to C++
In order to wrap the ATM routines by Python using TRIQS wrapping
tools it is necessary to modify the interface to 'dos_tetra3d'.
The major changes involved replacing direct NumPy arrays with
TRIQS arrays which can be converted to Python arrays using library
tools.

Also, some small changes were necessary to port the functions
from C99 complex numbers to C++ style.

CMakeList is added to automatize building of the ATM library.
