Description (last modified by )
The main goal of the patch was to add two functions namely arm_cells and leg_cells. On the way I found several bugs or inconsistencies:
Whereas the various cells methods returns the cells as tuple (i,j) Partition.corner used to return them as lists [i,j]. I changed them to return tuples. Various methods had to be fixed methods accordingly...
On the way I found that Tableaux.slide which uses Partition.Corner was modifying it's argument.

Hi Florent,
Thank you for this patch. Here are a couple of comments:
- Please use consistently "in English convention" instead of "in english notations",
see line 840, 963, 924.
- Would it be possible to lift the methods arm_length, leg_length, hook_length, arm_cells, etc also to SkewPartitions?? I recently needed those and it would be convenient to have them directly in Sage.
Cheers,
Anne

Except for cells which I just added, they are all accessible through l.outer().arm_length... So I'm not sure we wan't to link all of those.

I reviewed the patch. It cleans up several features in partitions. In addition it fixes the slide method in skew_tableaux and adds the cell method to skew_partitions as requested. All tests pass. Positive review!
Release manager, please apply only trac_6655_partition_corner_cells-fh.patch and trac_6655_partition_corner_cells-review-as.patch (in this order).
