Comment:
This patch fixes three bugs.
First, there is the bug originally reported in this ticket.
Second, there is the bug described at
http://groups.google.com/group/sage-combinat-
devel/msg/bce932c675b8b04a?hl=en
Third, it fixes an exception on
{{{Partition([]).outside_corners()}}}.
In addition there are a lot of documentation improvements.
The new class CrystalOfWords needs a docstring. Otherwise I found no
problems.
The patch does not change the effect of {{{sage --testall}}}.
The patch applies cleanly on sage-3.4.1.rc1.
Patch summary:
{{{
Adds index_set as a lazy_attribute method in class Crystal.
Removes class AffineCrystal which was prematurely implemented
Replaces the cmp_elements method => lt_elements in
ClassicalCrystalOfLetters.
Implements __ne__, __lt__, __ge__ methods in class Letter.
Properly indents docstrings for TensorProductOfCrystals.
New class CrystalOfWords.
FullTensorProductOfCrystals inherits from CrystalOfWords.
call method of FullTensorProductOfCrystals is taken down.
CrystalOfTableaux inherits from CrystalOfWords.
Docstring revision for CrystalOfTableaux.
CrystalOfTableaux __init__ method allows multiple shapes.
CrystalOfTableaux gets new methods cartan_type and module_generator
CrystalOfTableauxElement __init__ revisions
}}}
