          //we need to expand out the condition so it is in the form of a single OrCondition
          //that contains only AndConditions.  We do this by following the rules of boolean
          //algebra.  As an example, suppose the current condition is ((a=1 and b=2) or (c=3 and d=4)).
          //Suppose "other" is ((e=5 and f=6) or (g=7 or h=8)).  The overall condition, after applying the
          //"and" is:
          //
          //((a=1 and b=2) or (c=3 and d=4)) and ((e=5 and f=6) or (g=7 and h=8))
          //
          //This needs to be expanded out to remove the nested or clauses.  The result of this expansion is:
          //
          //(a=1 and b=2 and e=5 and f=6) or
          //(a=1 and b=2 and g=7 and h=8) or
          //(c=3 and d=4 and e=5 and f=6) or
          //(c=3 and d=4 and g=7 and h=8)
  
          //The logic below does this expansion, in a generalized way.  It loops through the existing AndConditions
          //and, in a nested loop, through the AndConditions in "other".  For each of those combinations,
          //it creates a new AndCondition that combines the two AndConditions together.  These combined
          //AndConditions become the new set of AndConditions in this OrCondition.
