grouping array

[pkilambi at gmail.com]

fredrick's solutions seems to be more closer to what I was looking
for.But I am still not sure if that could be done without the use of
Image module.
Also in your solution I cannot follow this
[[1, 1, 2, 1, 2, 0],
   [2, 0, 0, 2, 0, 1],
   [1, 2, 2, 0, 2, 0],
   [0, 1, 0, 0, 0, 0],
   [2, 0, 0, 1, 1, 0],
   [2, 2, 2, 0, 1, 0]]
  >>> print "\n".join(str(reg) for reg in getregions(x))
  [(0, 1), (0, 0), (0, 2), (1, 0), (0, 3), (2, 0), (1, 3), (0, 4), (2,
1), (3,
1), (2, 2)]
  [(5, 4), (4, 4), (4, 3)]
  [(5, 0), (5, 1), (4, 0), (5, 2)]
  [(1, 5)]
  [(2, 4)]
This is kind of confusing...could you please correlate the grid to the
result and explain
