//_HADES_CLASS_DESCRIPTION 
////////////////////////////////////////////////////////////////////////////////
//  HDetector
//
//  class to store the actual setup of a detector
//
//  The setup is defined in the macro via the memberfuntion
//  setModules(Int_t sector,Int_t* modules). The array must
//  have the size of the maximum mumber of modules in a
//  sector for this detector. If the module if not active the
//  according number is 0.
//  e.g. for Mdc:   Int_t mod[4]={1,2,0,0};
//                  mdc.setModules(0,mod);
//       This activates the modules 1 and 2 in sector 0
//  Detectors without a sector wise segmentation as e.g. the Start detector
//  use sector = -1.
//
//  It also holds the intelligence to build tasks related to this particular
//  detector as well as to create data structures for it.
//
//  This intelligence is stored in the functions: buildTask() and 
//  buildCategory() and has the form of compiled C++ code.
//
//  The function HTask *HDetector::buildTask(Text_t *task, Option_t *opt) 
//  builds a task object corresponding to the task identified by the string
//  "task". This can be an atomic task (a HReconstructor) or a set of them, in
//  this case the tasks will be packed in a HTaskSet so that buildTask() returns
//  a pointer to that HTaskSet. "opt" is a string where extra options can be 
//  given; the available options differ from detector to detector.
//
//  The function HCategory* HDetector::buildCategory(Cat_t cat) uses the
//  setup information in the HDetector to build a category object. The category
//  class and it's setup will be defined by "cat"; i.e. the HDetector has built
//  in the information of which category subclass is recommended for each kind
//  of data.
