Make it possible to define access restrictions for storage, scoreboard, etc.

[ChenCMD]

What about the ability to declare write / read-only to the scoreboard and storage? In solid development, you often want to allow references, but not rewrites. It is very troublesome to prepare an accessor function for that purpose.

I haven't come up with the syntax for that yet:(

[SPGoding]

How about just a @readonly annotation in our IMP-doc flavor?

[ChenCMD]

I think it's good, but I think it can be redundant to create complex access restrictions such as readonly from directory A and writeonly from directory B.
