Class Description

 The Frame conditions formula class                                   
                                                                      

*-*-*-*-*-*-*-*-*-*- Copy this condition formula -*-*-*-*-*-*-*-*-*-*-*-*-*
*-*                  ===========================

*-*-*-*-*-*  Check if name is in the list of conditions      *-*-*-*-*
*-*        ==================================================

   This member function redefines the function in TFormula
   If a condition has a name corresponding to the argument name, then
   returns a new code.
   A VConditionFormula may contain more than one variable.

   name can be :
      - Condition_Name
      - Condition_Name.Variable_Name

   Variable name can be a standard name like "amplitude" or any of
   the var names defined for the condition. The standard names
   are defined in VConditionFormula::CheckStandardVar
   If variable name is omitted, it is assumed to be "amplitude"

 Checks that the name of the condition variable is a standard one.
 Accepts a name that is not complete, provided it is not ambiguous
 Returns a number indicating the variable :
   1 = "timeBefore",
   2 = "timeAfter",
   3 = "triggerStatus",
   4 = "amplitude",
   5 = "probability"
   6 = "boolean, trigger exists or not" used in DefinedVariable()
   0 = no match

*-*-*-*-*-*-*-*-*-*-*Evaluate this condition formula*-*-*-*-*-*-*-*-*-*-*-*-*
*-*                  ===============================
 The formula applies to the conditions last loaded by the database

*-*-*-*-*-*-*-*-*-*-*Evaluate this condition formula*-*-*-*-*-*-*-*-*-*-*-*-*
*-*                  ===============================
 The formula applies to the current conditions in the condition set "condset"

*-*-*-*-*-*-*-*-*-*-*Evaluate this condition formula*-*-*-*-*-*-*-*-*-*-*-*-*
*-*                  ===============================
 It is supposed that the formula applies to the array of conditions "lcond"
