Detailed Description

The basic description of spacegroup asymmetric unit.

Only xmin,xmax,ymin,ymax and zmin,zmax are recorded, thus resulting in a parallelepipedic unit with one (0,0,0) corner. It is not really 'asymmetric' since more than the crystallographic asymmetric unit can be included in it.

Todo:

Currently the initialization of the asymmetric unit is done numerically, slowly. A faster algorithm should be used (using dichotomy), or we could switch to using a table of asymmetric units.
