Comment:

 I'm uploading a rebased (on sage-4.6) patch which modifies printing in
 class fields to not print the structure when size is 1, fixes some caching
 bugs, updates several doctests, etc...

 However, this happens, and I'm not sure whether this is okay or not:

 {{{
 sage -t sage/rings/number_field/number_field_ideal.py
 **********************************************************************
 File "/home/rlmill/sage-4.6/devel/sage-
 main/sage/rings/number_field/number_field
 _ideal.py", line 1017:
     sage: I._S_ideal_class_log([])
 Expected:
     [3]
 Got:
     [1]
 **********************************************************************
 }}}
