Created the base for tictactoe.controller and the api
The create controller is now connected to everything, now it just needs to be tested correctly
Testing if createGameController returns a non empty array
All unit tests pass, createGameController is not yet implemented
Added files and a base implementation for an eventStore. tictactoeController is now functional, but it is possible to pass all the unit tests without tictactoeController really doing anything
Added unit tests for memoryStore
MemoryStore unit tests fixed and implemented
Events are now stored properly
Added a unit test for tictactoeCommandHandler
Implemented containsEvent()
Used containsEvent everywhere it should be used
