Identify runs in list

[skorpio11 at gmail.com]

Hi all,

I have a data structure in a list as in: [0 0 0 3 0 5 0 0 0 0 1 0 4 0
5 0 0 7 0 0 0 0 0 12 0 0 4]

I would like to extract three list from this data:

1) runsOfZero: [3 4 5]
2) runsOfNonZero: [3 8 4]
3) SumOfRunsOfNonZero: [8 17 16]

Any suggestions would be appreciated
