class HMdcBArray

 list - list of layers: 6 bits, one bit per layer

 list - list of layers: 6 bits, one bit per layer

 return: >=0 - ok.!;

 return: -1 - num.cells=0

 return: >=0 - ok.!; -2 - num. of cells =0

 prPos <0 eq. first
 return: -1 next is absent

 The function search next seted bit after prPos in array, unset this
 bin and return a position of this one.
 The bit prPos must be unseted (=0), if not - function will return
 the same position!
 prPos <0 = seach first seted bin
 return: -1 next is absent

 prPos >size = start from latest bit
 return: -1 previous is absent

 The same as nextAndUnset but do it back order.
 prPos >= (pL-pF+1)*8 = start from latest bit
 return: -1 next is absent

 pF - pointer to first el., pL - pointer to last el.
 pS - pointer to el. which must be moved to *pL ((pL-pS) - shift)

 pT - pointer to first el., pL - pointer to last el.
 pS - pointer to el. which must be moved to *pT

Returns 1 if bit is seted, 0 if not

 Bit n=pos will unseted.
 Returns kTRUE if bit was seted, kFALSE if not

 Function produce list of identical for pF1 & ppF2 bits - pOut
 return number of identical bits

 Function produce list of identical for pNoId & ppEx bits - pIdnt
 and unset identical bits in pNoId
 return number of identical bits
   Int_t nIBits=0;
   const UChar_t *pExEnd = pEx + nBytes;
   for(;pEx<pExEnd;pEx++,pIdnt++,pNoId++) {
     *pIdnt  = *pNoId & *pEx;
     *pNoId ^= *pIdnt;
     nIBits += nBitLookUp[*pIdnt];
   }

 Function produce list of nonidentical for pF1 & ppF2 bits - pOut
 return number of not identical bits in pF1 and pF2
