class TSQLStructure: public TObject

  This is hierarhical structure, which is created when data is written
  by TBufferSQL2. It contains data all structurual information such:
  version of written class, data memeber types of that class, value for
  each data memeber and so on.
  Such structure in some sense similar to XML node and subnodes structure
  Once it created, it converted to SQL statements, which are submitted
  to database server.

 provides class info if structure kSqlStreamerInfo or kSqlCustomClass
const char* GetValue()
 returns value
 for different structure kinds has different sense
 For kSqlVersion it version, for kSqlReference it is object id and so on
void Add(TSQLStructure* child)
 Add child strucure

void AddValue(const char* value, const char* tname = 0)
 Add child structure as value
Long64_t DefineObjectId(Bool_t recursive = kTRUE)
 defines current object id, to which this structure belong
 make life complicated, because some objects do not get id
 automatically in TBufferSQL, but afterwards

 define maximum reference id, used for objects
Bool_t ConvertToTables(TSQLFile* f, Long64_t keyid, TObjArray* cmds)
 Convert structure to sql statements
 This function is called immidiately after TBufferSQL2 produces
 this structure with object data
 Should be only called for toplevel structure

 tries to store element data in column
Bool_t TryConvertObjectArray(TSqlRegistry* reg, TSqlRawBuffer* blobs)
 tries to write array of objects as lis of object refereneces
 in _streamer_ table, while objects itself will be stored in
 other tables. If not successfull, object data will be stored
 in _streamer_ table
Bool_t CheckNormalClassPair(TSQLStructure* vers, TSQLStructure* info)
 check if pair of two element corresponds
 to start of object, stored in normal form
Bool_t StoreTObject(TSqlRegistry* reg)
 store data of TObject in special table
 workaround custom TObject streamer
Bool_t StoreTString(TSqlRegistry* reg)
 store data of TString in special table
 it is required when TString stored as pointer and reference to it possible
Bool_t RecognizeTString(const char*& value)
 prove that structure containes TString data
Int_t DefineElementColumnType(TStreamerElement* elem, TSQLFile* f)
 defines which kind of column can be assigned for this element
 Possible cases
    kColSimple       -  basic data type
    kColSimpleArray  -  fixed arary of basic types
    kColParent       -  parent class
    kColObject       -  object as data memeber
    kColObjectPtr    -  object as pointer
    kColTString      -  TString
    kColRawData      -  anything else as raw data
TString DefineElementColumnName(TStreamerElement* elem, TSQLFile* f, Int_t indx = 0)

Int_t LocateElementColumn(TSQLFile* f, TBufferSQL2* buf, TSQLObjectData* data)
 find column in TSQLObjectData object, which correspond to current element
Bool_t UnpackTObject(TSQLFile* f, TBufferSQL2* buf, TSQLObjectData* data, Long64_t objid, Int_t clversion)

 Unpack TString data in form, understodable by custom TString streamer
void AddStrBrackets(TString& s, const char* quote)
 adds quotes arround string value and replaces some special symbols
const char* GetType()
{ return fType.Data(); }
TSQLStructure* GetParent()
{ return fParent; }
void SetParent(TSQLStructure* p)
{ fParent = p; }
void SetType(Int_t typ)
{ fType = typ; }
Int_t GetArrayIndex()
{ return fArrayIndex; }
Int_t GetRepeatCounter()
{ return fRepeatCnt; }
