The first part of the program consists of calculating
the most important (>30) conics of which a Laue
diffraction pattern is built. Starting with a peak search,
the procedure NODIRAX (normalized direct axes) should
end with a list of conics, where each conic is characterized
by a normalized direct lattice vector ( ndlv), the number
of spots contributing to the ndlv, and a 
value, telling
how well the spots fit to one conic.
