/*
* SetCellneighbours is used to set the neighbours for each Cell and then pass them in as a array of cells.
* Loops through the CellGrid checking which postion the Cell is at eg. in a corner or against the side.
* If in a corner or agasint a side then it takes the neighbour from the opposite side so as to make the grid wrap around.
* e.g. making the top and bottom neightbours as well as the left and right.
* Code is not as nice as how i would like it. I was unable to figure out how to use a Enum to refrence the number in the array instead.
