// ( see hgeantinput.h) and Connects the input-source, a file or the

// If the file has the extension .db or .DB or no extension the
// geometrical information will be read from database
// The information which input-source is actually used is stored in the
// element inputFlag as 'f' for file and 'd' for database. It's used
// in the further programm the select the read-routines.

// ns is the number of sectors. It is set to 6 in the constructor.
// WARNING: If ns is changing, there might be some problems when reading
//          and creating the geometry. To avoid these problems one should
//          use the inout-flag in the geometry_file of the sectors to
//          create only the desired sectors.
// The array nsSet stores the inout-flag of the sectors.
// ( If (nsSet[i]==1) sector i is actually created. The array is filled
// in the routines readDet(...) in hgeosect.cc.
