specify column which value should be varified before sending to server

• ind - column index (0 based)
• verifFunction - function (object) which should verify cell value (if not specified, then value will be compared to empty string). Three arguments will be passed into it: value, row ID and column index

   //check if first column values is not equal to 0
   myDataProcessor.setVerificator(0,greater_0);
   function greater_0(value){
	return value>0;
   }
 
   //check if second column values is not empty
   myDataProcessor.setVerificator(1,not_empty);
   function not_empty(value,id,ind){
	if (value=="") mygrid.setCellTextStyle(id,ind,"background-color:yellow;");
	return value!="";
   }
