Old description:

> a method returns a list of boxes in the arm.
> and so more.
New description:
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.
