Details:

The title says it all: isequal doesn't call overloaded isequal on struct
fields.

Here is an example.


>> pkg install -forge stk  # currently, stk 2.2.1
>> pkg load stk
>> x = stk_dataframe (rand (3, 2), {'A' 'B'})

x = <3x2 stk_dataframe array>

   :         A         B
 * :  0.433623  0.516320
 * :  0.119426  0.044071
 * :  0.378124  0.801516


Now, using a breakpoint in @stk_dataframe/isequal.m, I can confirm that the
overload isequal is called in this case:


>> isequal (x, x)
ans =  1


but not in this case:


>> xx.a = x;
>> isequal (xx, xx)
ans =  0
