For one cell -- some combination of pseudo code and workable code below. The relevant part is .cellCells(). Searching the code for cellCells() should give you plenty of ideas.

Code:
 //label for cell ,eg. cell 1
label someCell = mesh.Cells[1]

//list of labels for neighbor cells
labelList neighborCells = mesh[someCell].cellCells();
