Method GetBit

avida-core/source/tools/cBitArray.h:150–154

For fast bit operations, we're not going to setup operator[]; instead we're going to have a GetBit and a SetBit commamd. For this raw version we're also going to assume that the index is within range w/o any special checks.

  // we're also going to assume that the index is within range w/o any special
  // checks.
  bool GetBit(const int index) const{
    const int field_id = GetField(index);
    const int pos_id = GetFieldPos(index);
    return (bit_fields[field_id] & (1 << pos_id)) != 0;
  }

  void SetBit(const int index, const bool value) {
    const int field_id = GetField(index);
