Class Description

                                                                      
 VConditionSet                                                        
                                                                      
 Class for managing sets of conditions, i.e. conditions               
 that may have overlap(s) in time.                                    
 A condition set is used as a selection and a pointer to a particular 
 point in time where the selection expression is verified.            
 It is used in sequential access of frames or vectors satisfying some 
 conditions. Suppose for example that one wants to access all the     
 frames that have triggered the condition "Trig3.amplitude>3", where  
 Trig3 is a condition (or trigger) defined in the frames.             
 If vd is a pointer to a valid info database containing               
 the information, one would do :                                      
                                                                      
 vega[] co = new VConditionSet(vd,"Trig3.amp>3")                      
 vega[] fr = frchannel->GetNextFrame(co)                              
                                                                      
 that would return him the first frame satisfying the condition.      
 Issueing fr = frchannel->GetNextFrame(co) repeatedly will return     
 sequentialy all the frames that satisfy the condition.               
                                                                      

   Condition set building method. Used by the constructors
   "infodb" is the parent infodatabase
   "condf"  is a condition expression used to determine the active conditions
   "selfs"  is a selection expression. Used in case one wants to follow a set
            of conditions, given another set is present.

  Jumps to the condition set that contains time "time" or the nearest
  next one. Loads the relevant conditions as current.
  returns 0 = error, 1 = OK

  Jumps to the condition set that contains time "time" and satisfies recorded
 formula or the nearest next one. Loads the relevant conditions as current.
  returns 0 = error, 1 = OK

  Jumps to the next condition set in time (with respect to current)
  if a selection is present, will also require that the next set
  intersects with the conditions forming the selection.
  WARNING : if a selection is used, it may happen to return twice the same
  set for two consecutive calls to NextSet(), in case more than one
  selection is intersecting with that set.
  returns 0 = error, 1 = OK

  Jumps to the next condition set in time (with respect to current)
  that verifies the condition formula if present.
  if a selection is present, will also require that the set
  intersects with the conditions forming the selection.
  WARNING : if a selection is used, it may happen to return twice the same
  set for two consecutive calls to NextSet(), in case more than one
  selection is intersecting with that set.
  returns 0 = error, 1 = OK

  Returns the start time of the overlap of this set of conditions

  Returns the end time of the overlap of this set of conditions

  Returns the start time of the overlap of this set of conditions
 including the conditions used for selection

  Returns the end time of the overlap of this set of conditions
 including the conditions used for selection

 Returns the result of the condition formula applied to the last condition set

 Returns the result of the selection formula applied to the last condition set

 Evaluates the formula for the current condition set.
 Useful in case of interactive use.

 Sets the condition "conditionnumber" as active

 Sets the condition "conditionnumber" as used for selection
