 The code runs in two modes.

 First mode:

  "python CSLgenerator axis(u v w) [limit]" ----->  Where the u v w are the

  "python CSLgenerator.py axis(u v w) [limit]" ----->  Where the u v w are the

  indices of the rotation axis such as 1 0 0, 1 1 1, 1 1 0 and so on. The limit

  is the maximum Sigma of interest.

  (the limit by default: 100)

 Second mode:

 "python CSLgenerator axis(u v w) basis sigma [limit]" -----> Where basis is

 "python CSLgenerator.py axis(u v w) basis sigma [limit]" -----> Where basis is

  either fcc, bcc, diamond or sc. You read the sigma of interest from the first

  mode run. The limit here refers to CSL GB inclinations. The bigger the limit,

  the higher the indices of CSL planes.
