The reading of the field map files in the 3D Opera file format has been extended:
  1) The lenght unit can also be specified in cm instead of in meters only.
  2) Only one octant (in Kartesian coordinate system) of the field map can be
	specified, and the field can be extrapolated to other octants (this
	depends on the symmetry of the field).
  3) First line of the field map does not have to be empty (but it can be).
  4) Documentation has been modified accordingly.
