Update Readme to point to Wiki for documentation.

Changed timeout type in KWAsyncVerifier to NSTimeInterval from NSUInteger to avoid compiler warning for clients using warnings on implicit conversions. If you pass in a negative timeinterval, you deserve unexpected behavior.
Merge pull request #71 from JohannesRudolph/master

Warnings with AsyncVerifier macros.
Modified the example builder tests to use the new block based transactional system and proceeded to make them pass. Also did the same with determining if one is on the simulator or an actual iOS device.
Merge pull request #75 from dented42/master

fixed KWExampleGroupBuilderTests
Fixed some small type errors that don't have any effect on iOS, but could cause problems if we were to build for OS X.
Fix for simulator detection.

Merge commit 'a688f9e3c8c9477ec0d7203467dceb7c4c2cee4b'
WIP: fix for issue #64, ensuring beforeAll and afterAll work as expected.
Keep the association of the example group with the invocation encapsulated within KWExampleSuite.
Rename KWExampleGroup to KWExample.
Taking a different approach to how contexts and examples are run.

The problem is that originally, contexts were run from the outside in, starting at the root and working down into nested contexts.

Now, however, each individual example is run one at a time by SenTest, outside of the context run, so we instead need to work out from each example.

Using a bit of clever recursive block behaviour and making KWContext aware of it's parent, we
can work out from an example all the way to the root context, run each beforeAll block just once, then each beforeEach block, traversing back down to the example again, running it and then doing the same for the after blocks.
Added some comprehensive examples of how before each/all hooks work and the order of execution.
Improved description for debugging.
Use an array instead of a set to make the spec order deterministic.
Get after hooks working properly.
