Changes in the Arbiter block: - now multiple initiator sockets are possible. These intiator sockets connect to multiple memory controllers; - added lots of comments to the code in order to make it easier to understand. Changes in Simulaton[cpp,h]: - added TODO messages in some points that need to be changed to provide full support to multiple memory channles/controllers based on configuration.
