Detailed Description
A SOBasis object describes the transformation from an atomic orbital basis to a symmetry orbital basis.
The cental concept here is "SO shell". An SO shell is defined as a collection of symmetry-adapted basis functions that arise from one set of AO shells related by symmetry (an AO shell orbit). Thus the number of SO shells = the number of symmetry-unique AO shells, and each SO shell contains basis functions of potentially several symmetries.
