Solve any sudoku puzzle with just three simple steps

Solving a sudoku puzzle with three basic techniques -
1. identifying possible numbers in each cell and finalizing cells with single possible value
2. identifying possible numbers in each cell and finalizing numbers that occur only once in row, column or 3x3 box
3. repeating above two steps over and over again until all the cells are filled. if there are no single-possible numbers for cells and no single-occurance numbers for row, column and 3x3 box, try with each possible value and solve the board

Delay was purposefully introduced while updating cells to slow down for animation, actual solution takes fraction of second to calculate
