These comments will be skipped until the first integer value.							
Each row contains description of one event: features vector and its classification according to values of three cathegorical variables.							
"Values of the cathegorical variables can be proceeded by any number of spaces and tabs; they will be skipped."							
Remember! All cathegorical variable values can be encoded with ONLY ONE character!!							
First integer number greater than 0 will be interpreted as number of events (eventNbr).	Every trailing nonvisual signs, spaces and other chars proceeding 0 (#48) will be skipped here.						
Second one, in the next row, will be interpreted as number of vectors components  (nc).							
Third one, in the next row, will be interpreted as  components values range.  It is necessary for input visualisation during data reading.							
Next row is the table header. Cathegorical variable names are read from here.							
First four columns will be interpreted as cathegory, classyfing values (values of the four dependent variables).							
Next nc (here nc=3) columns will be read as vectors components.							
Prepare data file with MS Excel and export it as a txt file to avoid unnecessary characters.
