[out] = CELLFLAT(celllist) searches every cell element in cellist and put them on the top most level. Therefore, CELLFLAT linearizes a cell array tree structure.

V2.0 -
1. The default behavior does not change.
2. Additional parameter for flatten cell arrays up to N level
cellflat(C,N) flatten cell array C for up to N level (N level search/flatten). The default value is N = -1.
3. Compatible to all Matlan versions.

very handy, great submission

Thank you Iwo Bohr for valuable comment. Although error would generate if the input arguments is not a cell, I think this is useful to prompt users for the correct format. I've added the check and error message to my code.

Very nice and useful submission. I would add one short sanity check in case of supplying an argument which is not a cell array:

if ~iscell(celllist);error('the argument must be a cell array');end
