//aim: to define the trigger bits we are interested in
//implimentation: likely to be more than 32 (or even 64 bits) so differs from CutCodes in the fact it stores the bit position, not the bit mask

//unforunately hard coded limit of 64 bits which needs to be checked when setting it up
//if this becomes a problem, will be replaced by boost::dynamic_bitset
//my appologies for the typedef, it was better this way
