public interface Grid
```
A grid is a data structure containing numeric data organized in rows and columns. Cell 0,0 represents a real location x0, y0, and every cell has a width (dx) and a height (dy) so that a cell at row i and column j represents a location of coordinates
- x = j*dx+x0
- y = i*dy+y0
The main grid parameters are :
- The number of columns (c) and rows (r) (with a total number of values in the grid equals to c * r)
- x0, y0, the real coordinates of the grid cell at column 0, row 0
- gridWidth and gridHeight, which represent the real grid width and the real grid height
