ozMiddlewareL2

Contract in charge of forwarding the call from each Account (ozAccountProxyL2) to ozDiamond.

The main reason of its implementation is to change the msg.sender on each call, and produce a unique sender for all Accounts of the system, in order to have an unified caller to check in ozDiamond, and in this way, avoid unauthorized calls to the main entry function (exchangeToAccountToken()).
