Lables of checkerboard plot in example of mcnemar_table do not match the documentation

Describe the documentation issue

https://rasbt.github.io/mlxtend/user_guide/evaluate/mcnemar_table/#example-2-2x2-contingency-table

The labels of the checkerboard plot do not seem to match the description of the returned value

tb is

array([[4, 1],
       [2, 3]])

from returns in https://rasbt.github.io/mlxtend/user_guide/evaluate/mcnemar_table/#api

2x2 contingency table with the following contents: a: tb[0, 0]: # of samples that both models predicted correctly b: tb[0, 1]: # of samples that model 1 got right and model 2 got wrong c: tb[1, 0]: # of samples that model 2 got right and model 1 got wrong d: tb[1, 1]: # of samples that both models predicted incorrectly

• 4 (tb[0, 0], a) is # of samples that model 1 and 2 got right
• 1 (tb[0, 1], b) is # of samples that model 1 got right and model 2 got wrong
• 2 (tb[1, 0], c) is # of samples that model 2 got right and model 1 got wrong
• 3 (tb[1, 1], d) is # of samples that model 1 and 2 got wrong

Suggest a potential improvement or addition

I think that reversing each labels will work.

brd = checkerboard_plot(tb,
                        figsize=(3, 3),
                        fmt='%d',
                        col_labels=['model 2 right', 'model 2 wrong'],  # As is: ['model 2 wrong', 'model 2 right']
                        row_labels=['model 1 right', 'model 1 wrong'])  # As is: ['model 1 wrong', 'model 1 right']

Start with the linked mcnemar_table documentation example and its API return description, then compare the checkerboard_plot row and column labels with the returned array. Update the labels or accompanying documentation so the four values match, and verify the rendered example and descriptions agree.
