This form should print errors the default way.

>>> form1 = TestForm({'first_name': 'John'})
>>> print form1['last_name'].errors
<ul class="errorlist"><li>This field is required.</li></ul>
>>> print form1.errors['__all__']
<ul class="errorlist"><li>I like to be awkward.</li></ul>

This one should wrap error groups in the customized way.

>>> form2 = TestForm({'first_name': 'John'}, error_class=CustomErrorList)
>>> print form2['last_name'].errors
<div class="error"><p>This field is required.</p></div>
>>> print form2.errors['__all__']
<div class="error"><p>I like to be awkward.</p></div>
