A class used to check the whether the actual output from a doctest
example matches the expected output. `OutputChecker` defines two
methods: `check_output`, which compares a given pair of outputs,
and returns true if they match; and `output_difference`, which
returns a string describing the differences between two outputs.

_do_a_fancy_diff (
self,
want,
got,
optionflags,
)
Should we do a fancy diff?

check_output
|
check_output (
self,
want,
got,
optionflags,
)
Return True iff the actual output from an example (`got`)
matches the expected output (`want`). These strings are
always considered to match if they are identical; but
depending on what option flags the test runner is using,
several non-exact match types are also possible. See the
documentation for `TestRunner` for more information about
option flags.

|
output_difference
|
output_difference (
self,
example,
got,
optionflags,
)
Return a string describing the differences between the
expected output for a given example (`example`) and the actual
output (`got`). `optionflags` is the set of option flags used
to compare `want` and `got`.
