A Frame represents a 10x10 cell region of the screen (and thus a 100x100 pixel region). Like the Cell, the position of the bottom left corner of the Frame tells us everything we need to know about the position of the rest of the Frame as well as all of the Cells it contains. Define a class named Frame which has the following behaviors:

• It can return the pixel that represents the Frame. Use the method signature:
  public Pixel getBottomLeft( )

• It can change the pixel that represents the Frame. Use the method signature:
  public void setBottomLeft( Pixel pi)

• It can return the center (pixel) of the Frame. Use the method signature:
  public Pixel getCenter( )

• It can return the corners (pixel) of the Frame. Use the method signatures:
  public Pixel getTopLeft( )
  public Pixel getTopRight( )
  public Pixel getBottomRight( )

• Given the row and colomn number of the cell, it returns the pixel of that specific cell. Assume the first cell is row 1, colomn 1 and the top right cell is row 10, col 10. If the row and col values are outside the boundary of the Frame , the method returns null. Use the method signature:
  public Cell getCell(int column, int row)

• The class also has a constructor that accepts a Pixel as an argument. Use the following method signature:
  public Frame(Pixel pixel)

• A default construction initializes the class with a Pixel value of 0, 0:

  public Frame()
