Decided to not use a 'simpler' interface as it was more confusing than anything
Alter some stuff
Add a test for the setex method taking a timeunit
Some modifications in the basic api
Add more unit tests
Add tests for the pub/sub system
Change the API so that the polling for pub/sub stuff is separate from the rest
Small refactorings for pub/sub
Remove unused stuff, change other things
Meh, better that way
Implement the SimpleRedisClient
Remove useless files
Fix the tests
