EToken2 is the main asset platform.
It talks to EventsHistory to store events, which in turn asks MultiAssetEmitter and EToken2Emitter for event definitions.
EventsHistory uses Ambi for admin access checks.
It talks to RegistryICAP to resolve ICAP addresses.
RegistryICAP uses Ambi for admin access checks.
It uses Ambi2 for admin access checks.
It talks to SyncFab (deployed separately for every asset) which in turn talks to Asset[AssetWithRevert] (deployed separately).

SyncFab is the ERC20 to EToken2 interface contract, entry point for asset users.
