class TMemStat: public TObject

 Supported options:
    "new" - start to collect memory allocations stamps
    "read" - analyze previously collected data
    "gnubuildin" - if declared, then TMemStat will use gcc build-in function,
                      otherwise glibc backtrace will be used

 Default: "read"
 Note: Currently TMemStat uses a hard-coded output file name (for writing/reading) = "memstat.root";

 destructor

 Add named stamp to the file

 Return distance of the mouse to the TMemStat object

 Draw the memory statistic
 call ::Report("?") to see possible options and meaning

 Private function
 disable printing of the predefined code sequence

 function called when clicking with the mouse on a TMemStat object

 TODO: Comment me

 Get memstat from tree

Display the stack trace info corresponding to the graph at cursor position px,py.

   PRIVATE: make code index accoring tbit mask

   PRIVATE: make code index according tbit mask

 make array of graphs

 make array of graphs

 Make graph

draw histogram of memory usage as function of stamp name
 NOT IMPLEMENTED YET

 Make dump of memory usage versus time

 make report for library

 Make a text description of the stamps
 create a array of TText objects

 Paint function

 Print information about n selected functions
 If the number of function selected is bigger than number n
 the only top (sorted accoring some creteria,) n are displayed
 e.g draw.SortCode(TMemStat::kAllocSize,TMemStat::kCurrent);

 print information for code with ID

 Print information about n selected stack traces
 If the number of function selected is bigger than number n
 the only top (sorted according some criteria) n are displayed
 e.g draw.SortCode(TMemStat::kAllocSize,TMemStat::kCurrent);

 print stack information for code with ID
 NOTE: if _deep is 0, then we use fStackDeep

 PRIVATE function
 process user option string for printing

 TODO: Comment me

 Report function
 Supported options:

 order     : 0 - increasing 1 - decreasing
 sortstat  : 0 - TotalAllocCount 1 -  TotalAlocSize  2 - AllocCount 3 - AllocSize
 sortstamp : 0 - Current 1 -  MaxSize  2 - MaxCount
 sortdeep  : (0-inf) number of info to print
 stackdeep : (0-inf) deepness of stack
 Example   : order 0 sortstat 3 sortstamp 0 sortdeep 10 stackdeep 5 maxlength 50

 reset all selections

 Change default values of the auto stamping
   autoStampSize  [in] - size of invoking STAMPs
   autoStampAlloc [in] - a number of allocations

 Getvalues for iven stamp

 TODO: Comment me

 select code with given mask
 contlib       - select only code containing contlib in library path
 contfunction  - select only code with function name containing contfunction
 oType         - logical operation - AND and Or is supported
 By default all code is enabled
