py.test refactor of the tests is underway
add a limit to the ParsedTemplates example (gotta pass some tests)
add a repr to the Operation Example
rename tests to test_operations; switch from 'name' to 'doc', make OperationExample's 'test' default outside of the __init__, and improve __repr__ and disp_name
switch OperationExample 'name' to 'doc' keyword-only argument
move default OperationExample test into test_operation and make py.test display a bit more informative with _TEST_TUPLES
