ok i should also note I know this method isn't fool
proof only works for things which have existing tests,
and wouldn't test for adding methods/classes etc..
but figured it might inspire people to write tests for
functionality which they are using...
I should probably also note that I have some code
around here which dlopens a .so and dumps all its
subclasses/class methods etc, should be fairly simple
to add method signatures/ivar layout, and change the
output format to .plist or something
