In current design, AsmMachine is a rigid type containing Box<AsmCoreMachine> directly. This is required in a sense that assembly VM needs to know the inner data structures of AsmCoreMachine so as to function. However, It also puts a restriction on AsmMachine: while you can do the following in Rust VM: ``` DefaultMachine<Foo<DefaultCoreMachine<...>> ``` as long as Foo implements SupportMachine via a newtype pattern, this is not possible on AsmMachine. However there are certain cases we need wrappers on `Box<AsmCoreMachine>` to customize behaviors. This commit introduces a a new trait `AsmCoreMachineRevealer` between AsmMachine and AsmCoreMachine, it provides a mean for users of AsmMachine to customize its behavior, while also requires the presence of AsmCoreMachine, so assembly VM can still function. If only Rust has generic specialization, we won't need to go through all those troubles...
